Leviticus 18:24, 25 Defile not yourselves in any of these things; for in all these the nations are defiled which I cast out before you…Ye shall therefore keep my statutes and my judgments, and shall not commit any of these abominations; neither any of your own nation, nor any stranger that sojourneth among you.
The things that defile the people and the community are sexual perversions like adultery, incest, homosexuality, and bestiality. These are abominations that defile, pollute, make unclean, dirty, filthy, impure and full of sin. These things are abhorrent to God and should be to us as well. These abominable things were widespread among the heathen pagan world.
These sins may seem harmless with no victims, but we take seriously the word defile not yourselves. Both we and the others involved are defiled and harmed in soul and spirit, even in body. There are no victimless sins against God. In truth, every sin defiles ourselves and the land we live in.
But the Lord cleanses us with the blood of the Lamb. By faith we respond to the forgiveness of God. We are cleansed of defilement. Therefore, we avoid defiling ourselves again and again. The blood of Jesus cleanses us from every sin, so thus we want to stop defiling ourself. Repentance must be daily.
