“Sanctify yourselves therefore, and be ye holy: for I am the LORD your God. And ye shall keep My statutes, and do them: I am the LORD which sanctify you.” Leviticus 20:7-8 (KJV)
Much of this in dealing with sexual abomination, and witchcraft of all sorts; and worship of idols (Molech, etc). In this reading is mentioned the abomination of homosexuality (18:22 and 20:13).
The first reference is commandment against it. The second is the judgment handling it. Of course there are other abominations – sexual and otherwise named with the same penalty of death. There is beastiality, family incest of all sorts, and the mystical arts, including sacrificing children in the fire to Molech (20:1-5).
The matter of the law shows that we are all under the law of death. There is mercy and there is grace for all people who will come to God through His Son Jesus Christ. In and through Christ we sanctify ourselves, being empowered by God’s Spirit to come out from the abominations of the world, and being holy, separate unto God.
“Be ye holy: for I am the LORD your God.”
Also read 1 Corinthians 10:19-22.
