1 Peter 1:13-16

So prepare your minds for action, be completely sober [in spirit—steadfast, self-disciplined, spiritually and morally alert], fix your hope completely on the grace [of God] that is coming to you when Jesus Christ is revealed. [Live] as obedient children [of God]; do not be conformed to the evil desires which governed you in your ignorance [before you knew the requirements and transforming power of the good news regarding salvation]. But like the Holy One who called you, be holy yourselves in all your conduct [be set apart from the world by your godly character and moral courage]; because it is written, “YOU SHALL BE HOLY (set apart), FOR I AM HOLY.” [Lev 11:44, 45; 19:2]
