Ephesians 4:13–24

¹³until we all reach the unity of the faith and the knowledge of the Son of God, to a mature man, to a measure of the maturity of the fullness of Christ, ¹⁴so that we may no longer be infants, tossed about by waves and carried about by every wind of teaching, by the trickery of people, by craftiness with reference to the scheming of deceit. ¹⁵But speaking the truth in love, we are to grow into him with reference to all things, who is the head, Christ, ¹⁶from whom the whole body, joined together and held together by every supporting ligament, according to the working by measure of each single part, the growth of the body makes for the building up of itself in love.

Appeal for New Behavior

¹⁷This therefore I say and testify in the Lord, that you no longer walk as the Gentiles walk: in the futility of their mind, ¹⁸being darkened in understanding, alienated from the life of God, because of the ignorance that is in them, because of the hardness of their heart, ¹⁹who, becoming callous, gave themselves over to licentiousness, for the pursuit of all uncleanness in greediness.

²⁰But you did not learn Christ in this way, ²¹if indeed you have heard about him, and you were taught by him (just as truth is in Jesus), ²²that you take off, according to your former way of life, the old man, who is being destroyed according to deceitful desires, ²³be renewed in the spirit of your mind, ²⁴and put on the new man (in accordance with God), who is created in righteousness and holiness from the truth.
