1 Peter 1:13-17

Therefore, with your minds ready for action, be sober-minded and set your hope completely on the grace to be brought to you at the revelation of Jesus Christ. As obedient children, do not be conformed to the desires of your former ignorance. But as the one who called you is holy, you also are to be holy in all your conduct; for it is written, Be holy, because I am holy. If you appeal to the Father who judges impartially according to each one’s work, you are to conduct yourselves in reverence during your time living as strangers.
