1 Peter 1:14-16, 22-23

as children of obedience, not fashioning yourselves according to your former lusts in the time of your ignorance: but like as he who called you is holy, be ye yourselves also holy in all manner of living; because it is written, Ye shall be holy; for I am holy.

Seeing ye have purified your souls in your obedience to the truth unto unfeigned love of the brethren, love one another from the heart fervently: having been begotten again, not of corruptible seed, but of incorruptible, through the word of God, which liveth and abideth.
