1 Peter 1:15-19

But be holy in all you do, just as God, the One who called you, is holy. It is written in the Scriptures: “You must be holy, because I am holy.” You pray to God and call him Father, and he judges each person’s work equally. So while you are here on earth, you should live with respect for God. You know that in the past you were living in a worthless way, a way passed down from the people who lived before you. But you were saved from that useless life. You were bought, not with something that ruins like gold or silver, but with the precious blood of Christ, who was like a pure and perfect lamb.
