And you shall be holy to Me, for I the Lord am holy, and have separated you from the peoples, that you should be Mine. (Leviticus 20:26, NKJV)
Have you ever read Leviticus? It is a detailed record of many of the laws God gave Israel concerning the priesthood, sacrifices and offerings, purification and moral living. The overriding theme of the book is “be holy, for I am holy” (Leviticus 11:45). The holiness of God is the compelling reason His people must be holy. Whether we speak of Israel under the Sinai law, or the whole world under the gospel of Christ, we cannot live unholy lives and then somehow demand that God accept us “as we are” and even reward us in our unholiness. Yet, that is the attitude of many toward God. The context of today’s verse commanded Israel to keep all the statutes and judgments of God “that the land where I am bringing you to dwell may not vomit you out” (Leviticus 20:22). Today, if God’s people neglect the salvation we have in Jesus Christ we will not escape an even worse punishment (Hebrews 2:1-3). Holiness demands we make a distinction between what is clean and unclean, what is sin and righteous, what is evil and good (Leviticus 20:25). God separated Israel so it would be holy before Him. We must separate ourselves from unholiness or we, like Israel, will be defiled and condemned (2 Corinthians 6:17-7:1).
