God’s Purpose for Sex: Sex Demonstrates Faithfulness

Let’s continue our seven-part series on the “Purpose for Sex.”

Read Part 1: Sex is Worship

Read Part 2: Sex is about Intimacy

When I participate in sex God’s way, it is an opportunity to experience intimacy with my spouse. When I experience this type of deep soul intimacy with my spouse, I am reflecting the type of intimacy that God wants with us, with our heart. Reflecting this type of intimacy brings Glory to God, an expression of worship. When I demonstrate sexual faithfulness with my spouse, this brings Glory to God, and therefore, is another way to express our worship to Him.

Another purpose that God has for sex is this: Sex demonstrates faithfulness.

Why I am blogging about this.

  1. Many of the men and students I have helped were not taught the true purpose of sex growing up, either in their homes or in church.
  2. Culture is teaching many false things about sex and its purpose.
  3. If I understand the purpose for sex, then I have a much better shot of understanding God’s boundaries.

The seven purposes of sex that I see outlined in Scripture:

  1. Sex is worship.
  2. Sex is about intimacy.
  3. Sex demonstrates faithfulness.
  4. Sex is intended to be a selfless act.
  5. Sex is for pleasure.
  6. Sex produces a Godly heritage.
  7. God honoring sex can only be heterosexual.

This blog will discuss how “Sex Demonstrates Faithfulness.”

God is Faithful. This is who He is. Even when we are faithless to Him, He is faithful to us (2 Timothy 2).

One of the ways He demonstrates that faithfulness is through the cross of Christ. Romans 5:8 tells us that Christ died for us when we were sinners. He didn’t die for us when we were faithful. He died for us when we were the exact opposite. That is amazing!

The Bible is broken up into two parts, the Old Testament and the New Testament. The Old Testament tells us quite a bit about God’s chosen nation, Israel.

One example of God’s faithfulness can be found in the book of Judges. The children of Israel would obey, and God was faithful. The children of Israel would disobey by being unfaithful (bowing down to other gods), and God would discipline them. As they are experiencing discipline, they would cry out to Him for freedom from the discipline they were experiencing. He could have chosen not to be faithful. They didn’t deserve for Him to be faithful, but He demonstrated His faithfulness to them by rescuing them. Amazing!

He has done this in my life. For years I chose to bow down to the idol of porn instead of bowing down to Jesus. He didn’t give up on me. He didn’t abandon me. He chose to be faithful. He stuck with me. He pursued me. He was faithful to me when I was faithless.

My wife has demonstrated this kind of faithfulness as well. I was unfaithful to her as I bowed down to porn. I was faithless, but she remained faithful. She didn’t give up on me. She didn’t abandon me. She stuck with me. She pursued me. She is an amazing woman– what a gift from God!

Faithfulness is supposed to be demonstrated through sex. This is one of the reasons why sex is contained to the heterosexual marriage bed. I can’t be faithful to God’s plan of heterosexual sex if I walk down the path of homosexuality. I can’t be faithful to God’s plan of sex if I have multiple sex partners along the way. I don’t just mean partners where intercourse took place; I mean partners where anything sexual takes place.

I can’t be faithful to God’s plan of sex if I am involved in porn or involved in sexting. I can’t be participating in masturbation and be faithful to God’s plan for sex. I can’t do these things prior to marriage, and I can’t do them while married.

Remember, I just mentioned my own porn struggle from my past. I am not throwing rocks here. God does forgive– I have experienced this!

Here are some passages of Scripture to read about this:

If you don’t know Christ:

If you do know Christ:

It’s not about throwing rocks. It’s about saying that we want to commit to being faithful in the context of sex and marriage. Genesis 2 talks about leaving parents and cleaving to your spouse. I want to connect with my wife, be one with my wife, and be faithful to my wife.

What does this mean if I am single?

I am going to choose to not participate in sexual sin. As a follower of Christ, I have the Holy Spirit in me. I can let Him empower my life so I can walk away from sexual temptation and sexual sin. I can choose to be faithful to God and abstain. I can choose to be faithful to my future mate.

If God does not provide me a future mate, then being faithful to God will be enough. How? He will demonstrate that faithfulness to the one who is single. Many I am connected with are single, and I know one person in particular who speaks to me of God’s faithfulness in the midst of her singleness. This can be done, and it’s a beautiful thing!

What does this mean if I am married?

When I choose to run away from sexual temptation, I am demonstrating faithfulness to my spouse. When I choose not to put myself in situations where I will be tempted, I am demonstrating faithfulness to my spouse. When I only participate in sex in the context of marriage with my spouse, then I am demonstrating faithfulness to my spouse. When I am demonstrating this faithfulness to my spouse, I am ultimately reflecting the faithfulness that God shows to me in all aspects of my life.

He is faithful, and I want to be faithful to Him. I want to be faithful to my wife. When I demonstrate faithfulness to my wife and ultimately, to God, then I am worshiping!

Let us all be thankful for the faithfulness of God, and may God empower us to demonstrate faithfulness when it comes to sex, as well as every other aspect of our life.

As I close, I am reminded of an old hymn by Thomas Obadiah Chisholm, Great is Thy Faithfulness.

Great Is Thy Faithfulness, Thomas Chisholm – 1925

Great Is Thy faithfulness, O God my Father!
There is no shadow of turning with Thee;
Thou changest not, Thy compassions, they fail not
As Thou hast been Thou forever wilt be.

Great Is Thy faithfulness,
Great Is Thy faithfulness,
Morning by morning new mercies I see;
All I have needed Thy hand hath provided
Great is Thy Faithfulness, Lord unto me!

Summer and winter, and springtime and harvest,
Sun, moon, and stars in their courses above,
Join with all nature in manifold witness
To Thy great faithfulness, mercy, and love.

Great Is Thy faithfulness,
Great Is Thy faithfulness,
Morning by morning new mercies I see;
All I have needed Thy hand hath provided
Great is Thy Faithfulness, Lord unto me!

Pardon for Sin and a peace that endureth,
Thine own dear presence to cheer and to guide,
Strength for today and bright hope for tomorrow
Blessings all mine, with ten thousand beside!

Great Is Thy faithfulness,
Great Is Thy faithfulness,
Morning by morning new mercies I see;
All I have needed Thy hand hath provided
Great is Thy Faithfulness, Lord unto me!

All I can say is amen and amen and amen!
