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.
“Holiness is the habit of being of one mind with God, according as we find His mind described in Scripture. It is the habit of agreeing in God’s judgment, hating what He hates, loving what He loves, and measuring everything in this world by the standard of His Word.” – J.C. Ryle
