I. God’s Design for Sexuality

A. Creation of Man and Woman in God’s Image

Genesis 1:27 (ESV) So God created man in his own image, in the image of God he created him; male and female he created them.

This important fact shows how valuable every person is because we are all made in God’s image.

This means that we’re like him in some ways. We can think, create, understand right and wrong, and have relationships. 

Also, the fact that there are men and women shows how God is both one and many at the same time.

Even though men and women are different, they are still equal. They have different roles and qualities, but they need each other and should treat each other with respect. 

Remembering that we’re made in God’s image reminds us to be like him in how we treat others and take care of the world. 

It shows us that everyone is important and valuable, so we should treat them with love and respect, just like God does.

Love & Respect

In marriage, this means that when a man and a woman get married, they make a complete team. They each have their strengths and ideas, which help them work well together.

Men and women are equal in God’s eyes, and this equality is important in marriage too. 

Husbands and wives should treat each other with respect, love, and fairness. They appreciate each other’s differences and work together as a team.

When it comes to sex in marriage, it’s not just a physical thing. It’s a way for husbands and wives to show love and trust for each other. 

They should always respect each other’s feelings and needs, making sure they both feel valued and cared for.

Overall, following God’s plan for sex in marriage means treating each other well and cherishing the special bond they share. 

It’s about showing love, respect, and kindness to each other, just like God does for us.

B. Marriage is the Foundation for Sexual Intimacy

Marriage is a central role in God’s design for human relationships. It serves as the foundation for sexual intimacy and the family unit. 

From the beginning, God established marriage as a sacred covenant between one man and one woman, intended to reflect the unity, love, and commitment found within the Godhead.

Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh.” 

Genesis 2:24

This passage describes the bond created through marriage, where two individuals are joined together in a lifelong union portrayed by mutual love, support, and companionship.

Marriage provides a framework for sexual intimacy within God’s intended boundaries, characterized by trust, security, and commitment. 

It protects the sacredness of sexual relationships and keeps sex the way it’s meant to be. 

The Bible is clear that sex was created to make babies and bring couples closer together. It also makes clear that people Should NOT use each other, treat each other like objects, or cheat on each other.

Marriage is also a reflection of Christ’s love for His Church

Husbands, love your wives, as Christ loved the church and gave himself up for her.

Ephesians 5:25

This selfless love is shown through selflessness, humility, and fidelity. It forms the basis for marital unity and spiritual growth.

In a world marked by shifting cultural norms and distorted views of sexuality, the biblical vision of marriage offers a timeless and transcendent standard for human flourishing.

It provides a context for the cultivation of intimacy, companionship, and shared purpose while upholding the sanctity and dignity of every individual involved.

C. Monogamy & fidelity in marriage

Monogamy and fidelity within marriage are foundational principles that help keep the marriage strong and special. 

Monogamy refers to the practice of being married to only one spouse at a time, while fidelity means spouses practice faithfulness, loyalty, and commitment to their spouse in all aspects of the marital relationship.


The concept of monogamy finds its roots in creation, where God established marriage as a lifelong union between one man and one woman.

Genesis 2:24 Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh.

This design shows that marriage is supposed to be a special bond where both partners are devoted to each other, enjoy each other’s company, and stay together.


Fidelity within marriage includes emotional, physical, and spiritual faithfulness to one’s spouse. 

It involves prioritizing the needs, desires, and well-being of one’s partner above all others, ignoring all others to support and protect the marital relationship.

Fidelity also means being honest, transparent, and trustworthy in all encounters and decisions, creating an atmosphere of mutual respect, security, and intimacy within the marriage.

Why we should practice Monogamy and Fidelity?

The practice of monogamy and fidelity within marriage creates stability, confidence, and emotional safety, laying a strong groundwork for personal development, and peace in the relationship.

Monogamy and fidelity also contribute to the well-being of children raised within a stable and loving family environment. This can lead to good grades in school, feeling good emotionally, and fitting in well with others.

Fidelity within marriage also serves as a powerful witness to the values of commitment, and sacrificial love in a world marked by shifting cultural norms and relational instability. 

By sticking to these beliefs, couples show that marriage is really important and special. They recognize that it’s something set up by God for people to thrive and be happy.
