Sexual immorality is in a category all its own. 1 Corinthians 6:18 – Flee immorality. Every other sin that a man commits is outside the body, but the immoral man sins against his own body. Now, I wanna be honest with you. The full understanding of what Paul is saying, I think, escapes us all, because you read some of the finest, most consistent commentaries of writers and you will see that they are all giving their ideas and inferences, but no one is really that sure [of] what is Paul saying. But I believe Calvin says something that really hits the heart of the matter. Paul now shows how much we ought to abhor fornication, setting before us the enormity of its wickedness and baseness. Now, he shows its greatness by comparison, that this sin alone, of all sins, puts a brand of disgrace upon the body. Is it not enough to know that whatever makes it so doesn’t really matter. But this one thing we know for certain- that sexual immorality is in a category all to itself, with regard to vileness and harm.
Another thing about sexual immorality. God’s displeasure about sexual immorality is revealed in that he killed 23,000 Israelites in one day, for their immorality. 1 Corinthians 10:8 – Nor let us act immorally, as some of them did, and twenty-three thousand fell in one day. And what stopped the plague? Fineas, one man with a lance. He takes it on and he drives a stake right through its heart,. Men and some, listen to me. I guess there was a time when these things would just be addressed to men, But it seems that women have become just as shameless as men. There’s only one way to deal with sexual immorality and that is, drive a stake straight through it. Have no mercy upon it. Sometimes I believe, as a matter of fact, I know, we look at Israel going into the land of Canaan and they were told, “Have no mercy whatsoever on these pagan tribes that will lead you astray to another god. Have no mercy at all! Show no tenderness.” Now, that was written for us. Not that we are to harm anyone, in any way. Never. Cause it’s not talking about the people out there. They’re not the problem.
It’s talking about the pagans in your own heart, that when you see anything, any pagan walking across, trespassing your heart, any pagan thought, any pagan idea, then have no mercy! Kill it! Grind it to powder. Drive a stake straight through its heart. Don’t tolerate it. Be severe with yourself. Deal with it. So many times, these types of things are taught and everyone gets together and hugs one another and sings kumbayah, that is not what needs to be done here! You need to know: this is terrible! And you need to fight it with everything you’ve got. Because the door to opportunity will be slammed shut until you do.
