In my Human Sexuality course last spring, I wrote a paper outlining my personal theology of sex. In it, I discussed the mysterious beauty of the act and how it reflects a unified, three-in-one God by unifying a two-in-one marital relationship. But I also spent one paragraph’s worth of space on its misuses because of the clarity and severity with which the Bible condemns certain sexual practices. Spoiler alert: it is grave. First Corinthians 6:18 implies the disease associated with sexual laxness. Galatians 5:19-21, Ephesians 5:5, and 1 Corinthians 6:9-10 warn that it precludes inheriting the Kingdom of God. Mark 7:20-23 labels it a “defiler” of the heart and mind. Hebrews 13:4 cautions that it ushers in the judgment of God. Revelation 21:8 identifies death as its natural consequence. God is relentless on this point: misuses of sex will never create joy for you. It will bring pain, destruction, and perhaps disease, but never joy.
But this is not an essay on poor sexual choices. This is about how big God’s grace must be because three kinds of sexual immorality are in his own genealogy. If stronger evidence of John 3:17 – that God came into the world not to condemn it but to save it – exists, I certainly don’t know where it is.
The first woman listed in the genealogy of Jesus is Tamar (Matthew 1:3), whose story is found in Genesis 38. She needed to produce an heir for her in-laws but found it impossible. Her first husband died, her second husband was deceitful and died as a result, and the third husband she was promised was never given to her. With a ticking biological clock, she dressed as a prostitute, knowing her father-in-law would proposition her. It happened, she got pregnant, and that boy ended up in the genealogy of Jesus.
The second woman listed in the genealogy of Jesus is Rahab (Matthew 1:5), whose story is in Joshua 2. She was an actual prostitute, not just for Halloween, who hid two of God’s men and saved them from certain death. After talking with them on the roof while they hid at her house, she declared her faith in Israel’s God. Her son is also an ancestor of Jesus.
The fourth woman listed is Bathsheba (Matthew 1:6), whose story is in 2 Samuel 11. By far, she has the most soap-operatic story of them all. King David sees her bathing and wants her immediately. They end up pregnant, which is a problem because Bathsheba is married. So David arranges for her husband to be killed in battle. A child resulting from their union, Solomon, is also in the messianic line.
Even more interesting: women just weren’t included in Jewish genealogies. Inspired by God, the author of Matthew went out of his way to make sure you know about Tamar, Rahab, and Bathsheba and their place in the line of Jesus.
So it’s true that sinful uses of sexuality are some of the evilest, gravest sins a person can engage with. But in Jesus’s own line, there is incest mixed with deceit; prostitution; and adultery mixed with murder. This is how God chose to get Jesus to us. There’s no way around the fact that sexual immorality leads to death. But when given to Jesus, even sexual immorality can result in life and hope and grace.
Furthermore, as serious as all sins are, God’s grace is even more serious about rescuing you and cleaning you out. God’s grace is serious about setting you free and filling you up with joy. That’s a force to carry you through anything, even the pain of turning to him after sin.
May you have the power to understand, as all God’s people should, how wide, how long, how high, and how deep his love is. May you experience the love of Christ, though it is too great to understand fully. Then you will be made complete with all the fullness of life and power that comes from God. — Ephesians 3:18-19
Nothing can ever separate us from God’s love. Neither death nor life, neither angels nor demons, neither our fears for today nor our worries about tomorrow—not even the powers of hell can separate us from God’s love. No power in the sky above or in the earth below—indeed, nothing in all creation will ever be able to separate us from the love of God that is revealed in Christ Jesus our Lord. — Romans 8:38-39
