Returning to God’s Design for Gender, Sexuality, Relationships, and Marriage
Primary Texts
Genesis 1:26–28
Genesis 2:18–25
Opening Illustration
Imagine a man who buys a highly advanced machine designed by expert engineers. The machine comes with a manual explaining exactly how it was meant to function.
But the owner decides he does not need the manual. He rearranges parts, removes components, and uses the machine in ways never intended by its designer.
For a short time the machine appears to work. But eventually the system begins to break down. Parts malfunction. The machine fails.
Finally the owner asks,
“Why does this machine not work?”
The answer is simple: the problem was never the design.
The problem was ignoring the designer.
This is precisely what has happened in our world.
God designed:
- humanity
- gender
- sexuality
- relationships
- marriage
Yet modern culture has attempted to redesign everything.
The result is confusion.
Tonight we return to the beginning of Scripture to rediscover God’s original design.
SERMON 1
God’s Design for Gender and Sexuality
Primary Text
Genesis 1:26–28
Purpose
To establish that gender and sexuality originate in God’s creation and therefore cannot be redefined by human preference.
Movement 1
Identity Is Given by the Creator
Genesis 1:27
“So God created man in his own image… male and female created he them.”
This verse answers one of the most important questions in human life:
Who determines what it means to be human?
The Bible gives a simple answer:
God does.
Human identity begins not with our feelings, culture, or personal choices, but with the Creator who made us.
This truth has several implications.
First, human beings are not self-originating.
None of us decided to exist. None of us designed our own nature before we were born. Every human life exists because God willed it into existence.
We are creatures. God is Creator.
Second, human beings are not self-defining.
When an engineer designs a machine, the machine does not decide its own purpose. Its design determines how it functions.
In the same way, God designed human nature.
He determined:
- what the human body is
- how reproduction works
- how men and women relate
- how families are formed
Human beings may reject that design, but they cannot recreate it.
Third, identity is something we receive, not something we invent.
Modern culture often teaches that identity should be discovered by looking inward. People are told that their deepest feelings define who they truly are.
But Scripture teaches the opposite direction.
We do not understand ourselves by looking only within.
We understand ourselves by looking upward to the Creator.
Identity is not created by the self.
Identity is received from God.
This is the foundation of the entire biblical view of gender and sexuality.
Movement 2
Humanity Exists as Male and Female
Genesis 1:27 again declares:
“Male and female created he them.”
This statement is remarkably simple, yet profoundly important.
The Bible does not describe humanity as an undefined spectrum.
It describes humanity as a twofold design.
Human beings exist as male and female.
This distinction is not a social invention. It is part of the biological and theological structure of creation.
Biologically, sex is defined by reproductive function.
Human reproduction involves two complementary reproductive cells:
- sperm
- egg
Because there are only two reproductive systems, there are only two biological sexes.
Every human body is structured toward one of these two reproductive roles.
Sometimes people point to rare developmental conditions, often called intersex conditions, as evidence of additional sexes. These conditions are real, but they do not represent a third reproductive system. They are variations or developmental irregularities within the male–female structure of human biology.
Scripture provides a theological explanation for such irregularities.
After the fall of humanity in Genesis 3, the created order became affected by corruption and disorder.
Romans 8 describes creation as “groaning.”
This brokenness appears in many forms:
- disease
- genetic disorders
- infertility
- developmental abnormalities
These realities do not redefine creation; they reveal the damage caused by sin.
Therefore the biblical view remains clear:
Humanity exists in two complementary forms—male and female.
Movement 3
Sexuality Was Designed for Covenant
Sexuality is not merely a biological function.
It is part of God’s moral design for human life.
Genesis 2:24 summarizes this design:
“A man shall leave his father and his mother and shall cleave unto his wife: and they shall be one flesh.”
This verse reveals the purpose of sexuality.
First, sexuality creates covenantal union.
Sexual intimacy is the physical expression of a lifelong covenant between husband and wife.
Second, sexuality enables procreation.
Through this union, new human life enters the world.
Third, sexuality forms families, which become the foundation of society.
In other words, sexuality was never designed for casual consumption. It was designed for covenant.
When sexuality is removed from covenant commitment, the connection between intimacy, responsibility, and family begins to collapse.
This is why societies that abandon God’s design eventually experience instability in relationships, families, and communities.
God’s design protects human flourishing.
Transition to Sermon 2
If Sermon 1 answers the question:
“Who are we as male and female?”
Sermon 2 answers the next question:
“How should men and women relate to each other?”
To answer that question we return to Genesis 2.
SERMON 2
God’s Design for Relationships and Marriage
Primary Texts
Genesis 2:18–25
1 Thessalonians 4:3–7
Purpose
To show how men and women should form relationships and prepare for marriage according to God’s design.
Movement 1
Marriage Is God’s Design for Human Partnership
Genesis 2:18
“It is not good that the man should be alone.”
This is the first statement in the Bible that something is “not good.”
The problem was not sin. Sin had not yet entered the world.
The issue was human incompleteness.
God designed human beings for relational life.
Therefore He created the woman as a partner who corresponded to the man.
When Adam sees her, he declares:
“This is now bone of my bones and flesh of my flesh.”
This moment establishes the first human marriage.
Genesis 2:24 then defines the structure of marriage:
A man leaves his parents,
cleaves to his wife,
and the two become one flesh.
Marriage therefore includes three elements:
- a new family unit
- a covenant commitment
- a deep personal union
Marriage is not a human invention.
It is a divine institution established by God.
Movement 2
Relationships Before Marriage Must Be Governed by Holiness
Because sexuality belongs to marriage, relationships before marriage must be guided by purity.
1 Thessalonians 4:3 states clearly:
“This is the will of God, even your sanctification, that ye should abstain from fornication.”
God does not forbid sexual immorality because He dislikes pleasure.
He forbids it because sexual intimacy is powerful.
Illustration:
Fire in a fireplace warms the house.
Fire in the middle of the living room burns the house down.
Sexuality within marriage blesses life.
Sexuality outside marriage destroys trust, damages relationships, and weakens future marriages.
Therefore relationships before marriage must be marked by:
- self-control
- respect
- moral boundaries
Holiness protects love from becoming destructive.
Movement 3
Marriage Reflects the Gospel
The New Testament reveals an even deeper meaning of marriage.
Ephesians 5:31–32 quotes Genesis 2:24 and then declares that marriage ultimately points to Christ and the church.
Marriage is therefore not only about companionship.
It is also a living picture of redemption.
The husband reflects Christ’s love for the church.
Christ’s love is marked by:
- sacrifice
- faithfulness
- protection
The wife reflects the church’s loving response to Christ.
When marriage operates according to this design, it becomes a visible testimony of the gospel.
In this way, marriage is not merely a social institution.
It is a sacred covenant that reflects God’s redeeming love.
Final Exhortation
Our culture is deeply confused about identity, sexuality, and relationships.
But confusion does not erase truth.
God created humanity male and female.
God designed sexuality for covenant.
God established marriage for human flourishing.
Sin has distorted that design.
But the gospel restores what sin has broken.
Through Jesus Christ:
- sins are forgiven
- hearts are renewed
- relationships can be healed
Therefore the church must hold two truths together:
truth about God’s design
and grace for broken people.
In a confused world, the church must point people back to the Creator.
Because the design is still good.
Below is the same sermon structure rewritten in simpler English, while keeping the three-movement structure and strengthening Sermon 2 around relationships and preparation before marriage.
The language is clearer, more pastoral, and easier to read while studying or preaching.
Conference Theme
Returning to God’s Design for Gender, Sexuality, Relationships, and Marriage
Primary Texts
Genesis 1:26–28
Genesis 2:18–25
Opening Illustration
Imagine a man who buys a very expensive and complicated machine. The manufacturer gives him a manual that explains exactly how the machine is supposed to work.
But the man decides he does not need the manual. He removes some parts, rearranges others, and begins using the machine the way he thinks it should work.
For a while it may seem fine. But after some time problems begin. The machine starts failing. Parts break. The whole system stops working properly.
Finally the man says,
“Why is this machine not working?”
The answer is simple.
The problem was never the design.
The problem was ignoring the designer.
This is what has happened in our world.
God designed human life.
He created gender.
He created sexuality.
He created relationships.
He created marriage.
But modern culture has tried to redesign everything.
The result is confusion.
The problem is not God’s design.
The problem is rejecting the Designer.
In this conference we will return to the beginning of the Bible to rediscover God’s design.
SERMON 1
God’s Design for Gender and Sexuality
Primary Text
Genesis 1:26–28
Purpose
To show that gender and sexuality come from God’s creation, not from human opinion or personal feeling.
Movement 1
Our Identity Comes From God
Genesis 1:27
“So God created man in his own image… male and female created he them.”
This verse answers an important question:
Who defines what it means to be human?
The Bible says the answer is God.
Human identity does not begin with our feelings or with culture. It begins with the Creator who made us.
First, human beings did not create themselves.
None of us chose to exist. None of us designed our own bodies before we were born. Every human life exists because God created it.
We are creatures. God is the Creator.
Second, human beings do not design their own nature.
When a machine is made, the designer decides how it works. The machine cannot choose its own purpose.
In the same way, God designed human nature.
He decided:
- what the human body is
- how reproduction works
- how men and women relate
- how families are formed
People may reject God’s design, but they cannot replace it.
Third, identity is something we receive, not something we invent.
Many people today believe identity is discovered by looking inward at their feelings or desires.
But the Bible teaches that we understand ourselves by looking to the One who made us.
We do not define ourselves.
We receive our identity from God.
Movement 2
God Created Humanity as Male and Female
Genesis 1:27 says clearly:
“Male and female created he them.”
The Bible describes humanity in two forms: male and female.
This is not a cultural idea. It is part of the structure of creation.
From a biological point of view, sex is connected to reproduction.
Human reproduction involves two types of reproductive cells:
- sperm
- eggs
Because there are only two reproductive roles, there are only two biological sexes.
Human beings are therefore male or female.
Sometimes people mention rare medical conditions where sexual development is unusual. These are real conditions, often called intersex conditions. But they do not create a third sex. They are variations in how the male or female body develops.
The Bible explains why such conditions exist.
After sin entered the world in Genesis 3, creation became affected by brokenness.
Romans 8 says creation is “groaning.”
Because of this brokenness, human bodies sometimes experience:
- disease
- infertility
- genetic problems
- developmental abnormalities
These conditions show that the world is fallen, but they do not change God’s original design.
God created humanity male and female.
Movement 3
Sexuality Was Designed for Covenant
Sexuality is not only physical. It is part of God’s moral design for human life.
Genesis 2:24 explains this design:
“A man shall leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.”
This verse teaches several important truths.
First, sexual union belongs in marriage.
Sexual intimacy expresses the deep union between husband and wife.
Second, sexuality allows human life to continue.
Through this union, children are born.
Third, sexuality forms families.
Families provide stability for children and strength for society.
This means sexuality was not designed for casual pleasure or temporary relationships.
Sexuality was designed for covenant commitment.
When sexuality is separated from marriage, people often experience broken relationships, emotional pain, and unstable families.
God’s design protects human life.
Transition to Sermon 2
The first sermon answered this question:
Who are we as male and female?
The second sermon answers another question:
How should men and women build relationships that lead to marriage?
To answer that, we look again at Genesis 2.
SERMON 2
God’s Design for Relationships and Marriage
Primary Texts
Genesis 2:18–25
1 Thessalonians 4:3–7
Purpose
To teach how unmarried believers should approach relationships and prepare for marriage in a way that honors God.
Movement 1
Relationships Begin With God’s Design for Marriage
Genesis 2:18
“It is not good that the man should be alone.”
This is the first time in the Bible that something is called “not good.”
The problem was not sin. Sin had not yet entered the world.
The problem was that human beings were created for companionship.
God designed people to live in relationship.
So God created the woman as a partner who corresponded to the man.
When Adam saw her, he said:
“This is now bone of my bones, and flesh of my flesh.”
Adam recognized that the woman was both like him and different from him.
Then Genesis 2:24 establishes the pattern for marriage:
“A man shall leave his father and mother, and shall be joined to his wife, and they shall become one flesh.”
Marriage therefore includes three important elements.
First, leaving.
Marriage creates a new family. The husband and wife form their own household.
Second, cleaving.
Marriage is a covenant commitment. It is not temporary. It is a lifelong union.
Third, one flesh.
Marriage unites two people emotionally, spiritually, and physically.
Marriage is therefore not a human invention.
It is God’s design.
Movement 2
The Time Before Marriage Is a Time of Preparation
Before marriage, people often form romantic relationships.
This season of life is very important because it prepares people for marriage.
Singleness is not a meaningless stage of life. It is a time for growth and preparation.
A healthy marriage usually comes from two people who have prepared themselves spiritually and personally.
Preparation includes:
- spiritual maturity
- self-control
- responsibility
- wisdom
A person should not only ask,
“Who should I marry?”
They should also ask,
“Am I becoming the kind of person who is ready for marriage?”
The time before marriage should be used to grow in character and devotion to God.
Movement 3
Relationships Before Marriage Must Be Pure and Purposeful
1 Thessalonians 4:3 says:
“This is the will of God, even your sanctification, that ye should abstain from fornication.”
This means sexual purity must guide relationships before marriage.
Sexuality is powerful, and it was designed for the covenant of marriage.
A helpful illustration is fire.
Fire inside a fireplace warms the house.
Fire in the middle of the living room burns the house down.
Sexual intimacy inside marriage strengthens love.
Sexual intimacy outside marriage damages relationships and creates regret.
Because of this, relationships before marriage must be guided by holiness.
They must also be purposeful.
A romantic relationship should not exist only for entertainment or emotional excitement.
Its purpose should be to consider whether two people could build a godly marriage together.
Important questions include:
- Do we both love Christ?
- Are we growing spiritually?
- Do we share the same values and direction in life?
The Bible also warns believers not to marry unbelievers.
2 Corinthians 6:14 says:
“Be ye not unequally yoked together with unbelievers.”
Marriage requires spiritual unity.
If two people follow different spiritual paths, their marriage will struggle.
For this reason, shared faith should be more important than attraction or social status.
Final Exhortation
Our culture is confused about identity, sexuality, and relationships.
But God’s design has not changed.
God created humanity male and female.
He designed sexuality for covenant marriage.
He established marriage as the foundation of family and society.
Sin has damaged this design, but the gospel brings restoration.
Through Jesus Christ:
- sins can be forgiven
- hearts can be changed
- relationships can be healed
The church must therefore hold two truths together:
truth about God’s design
and grace for broken people.
When we follow God’s design for gender, sexuality, relationships, and marriage, we discover that His design is wise, good, and life-giving.
If you want, I can also upgrade this sermon further in two powerful ways:
- Add stronger illustrations and emotional weight so it grips the audience more deeply.
- Add a very powerful closing appeal (3–4 minutes) that will make the conference end memorably.
