4:17 So I say this, and insist ⁶  in the Lord, that you no longer live as the Gentiles do, in the futility ⁷  of their thinking. ⁸  4:18 They are darkened in their understanding, ⁹  being alienated from the life of God because of the ignorance that is in them due to the hardness of their hearts. 4:19 Because they are callous, they have given themselves over to indecency for the practice of every kind of impurity with greediness. ¹⁰  4:20 But you did not learn about Christ like this, 4:21 if indeed you heard about him and were taught in him, just as the truth is in Jesus. 4:22 You were taught with reference to your former way of life to lay aside ¹¹  the old man who is being corrupted in accordance with deceitful desires, 4:23 to be renewed in the spirit of your mind, 4:24 and to put on the new man who has been created in God’s image ¹²  – in righteousness and holiness that comes from truth. ¹³
