1 Peter 1:13-16

Williams(i) 13 Therefore, as a means of spiritual preparation, tighten up the belt about your minds, keep perfectly calm, keep your hope on the spiritual blessing to be conferred upon you at the unveiling of Jesus Christ. 14 As obedient children, stop molding your character by the evil desires you used to cherish when you did not know any better, 15 but in accordance with the Holy Being who has called you, you must prove to be holy too, 16 for the Scripture says: "You ought to be holy, because I am holy."
