Deuteronomy 14:2a for you are a people holy to the Lord your God. (Holy is a word that means God has set us apart, has separated us out to Himself, has devoted us to Him, has chosen us as His Own, as a peculiar people, undeserving in ourselves, but selected by God Himself. He has chosen to separate us from our sin nature and separate us to His holiness and righteousness. Not only were these chosen people to be outwardly pure and holy, avoiding anything in their world that reflected the pagan practices of idol worship, but they were also to walk in an inward purity and holiness.
Their inward purity should result in outward purity, and their outward purity should come from their inward purity. Today, we, too, are a people holy to the Lord. Through a completely sovereign and independent act, He has separated us to Himself, made us holy to Him, calling us into both inward and outward purity, calling us away from the ways of the world and into obedience to Him, calling us into a walk with Him that results in our behavior and actions reflecting our inner commitment to the Lord.)
