Ephesians 4:17-28 New Revised Standard Version (NRSV)
The Old Life and the New
17 Now this I affirm and insist on in the Lord: you must no longer live as the Gentiles live, in the futility of their minds. 18 They are darkened in their understanding, alienated from the life of God because of their ignorance and hardness of heart. 19 They have lost all sensitivity and have abandoned themselves to licentiousness, greedy to practice every kind of impurity. 20 That is not the way you learned Christ! 21 For surely you have heard about him and were taught in him, as truth is in Jesus. 22 You were taught to put away your former way of life, your old self, corrupt and deluded by its lusts, 23 and to be renewed in the spirit of your minds, 24 and to clothe yourselves with the new self, created according to the likeness of God in true righteousness and holiness.
Rules for the New Life
25 So then, putting away falsehood, let all of us speak the truth to our neighbors, for we are members of one another. 26 Be angry but do not sin; do not let the sun go down on your anger, 27 and do not make room for the devil. 28 Thieves must give up stealing; rather let them labor and work honestly with their own hands, so as to have something to share with the needy.
