Take time to read 1 Corinthians chapter 6.
"Flee from sexual immorality. All other sins a man commits are outside his body, but he who sins sexually sins against his own body. Do you not know that your body is a temple of the Holy Spirit, who is in you, whom you have received from God? You are not your own, you were bought at a price. Therefore honor God with your body." 1 Corinthians 6:18-20
Sexual sins were rampant in Corinth. The temple of Aphrodite, the goddess of love, was in town and it employed over a thousand prostitutes as priest and priestesses. Sex was an important part of the worship of Aphrodite and I imagine they had no problems getting people to attend worship there.
Sex in worship was no doubt extremely appealing to those in Corinth and attracted worshippers from all around the world. But God called His people in Corinth to purity rather than promiscuity. So, Paul instructed the Corinthians to flee from sexual immorality. The temptation of sexual immorality was, and is, too great of a threat to flirt with. We are better off fleeing from sexual immorality than battling it head on.
This advice has been given to us time and again. You know to flee from sexual immorality. You know to set boundaries in your dating life. You know that you are to remain sexually pure until marriage.
Sex before marriage will have negative consequences in some way. Below are just a few facts that support that:
1) You'll have to tell your spouse about all you did with someone other than him/her. Shame may follow.
2) 50% of sexually active adults will get an STD before age 25. (According to the American Journal of Medicine 102 (5a) 3-8)
3) In 2008 there were 110 million prevalent STDs amongst American men and women.
4) Sex releases oxytocin which helps bond the two engaging in intercourse. The more people you have sex with the more likely you are to have a broken heart when each relationship or one night stand doesn't work out.
5) You defile the temple of the Holy Spirit.
These are just a few ways that sexual immorality hurts us. "He who sins sexually sins against his own body" is definitely true.
We are called to purity. God created sex for marriage and in marriage it is a very good thing. God calls us not to be a slave to sexual temptation, but instead to be a slave to Him. "You are not your own, you were bought at a price. Therefore honor God with your body."
Flee from sexual immorality of all kinds today.
