Holiness is the bible word that means "to separate". People don't like the word, because they don't understand it. It's to separate from sinful things & be closer to Godly things.

Holiness isn't personal perfection, its your gift to God &
yourself. Holiness brings you favor from God, credibility as His witness & strength against temptation.

Grace forgives our sins & helps our weakness, but holiness gives us dominion to represent God to our lost world. Pray to live holy, its the missing piece.
