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:  (for all these abominations have the men of the land done, which were before you, and the land is defiled;) that the land spue not you out also, when ye defile it, as it spued out the nations that were before you.  For whosoever shall commit any of these abominations, even the souls that commit them shall be cut off from among their people.
Leviticus 18:26-29

All of Leviticus 18 deals with sexual morality. Most of the first part is dealing with family members, such as the wife of your father, the sister of your father or mother, etc..

We get a bit of a glimpse into why the LORD is blessing Israel with the land of Canaan; that it is because of hundreds of years – over four hundred – of gross immorality. Such as offering children to their gods, like Molech, Baal, and so forth. Apparently, they were also committing adultery with their neighbors, practicing homosexual behavior, and beastiality.

God calls His people to be holy, as He is holy; and they are to keep His commandments, and His statutes. He says, I am the LORD your God.

The people in the land of Canaan, the land promised to Abraham, Isaac, and Jacob, needed cleansing, and God was going to cleanse it with blood. God warns His people that if they turn away from Him, and commit these sinful, atrocities, against Him, then, they also will be driven from the land, that it might be cleansed.

God’s people, Christians today, need to practice the call to be pure, and clean sexually before the Lord, and the world.

We are to be different, live differently, and we too are called in God’s word to be holy because God is holy (1 Peter 1:16).

The way to holiness is by way of the faith of Jesus Christ. He died for us, becoming sin for us, and receiving the wrath of God; that was what I myself and you deserved; and died in our stead. He was buried, and He rose again. When we put our faith, and trust in Him He makes us righteous and holy before Him.

We are to hate evil in every form.  We first look inside of self, and hate our own to start with. As we draw nearer and nearer to God we begin to see our sin, and deal with that, and let God deal with other’s evil.

Do you know Jesus Christ? If not call out to Him in repentance, and faith, and He will hear you and give you eternal life.
