[and He did this] to fully equip and perfect the saints (God’s people) for works of service, to build up the body of Christ [the church]; until we all reach oneness in the faith and in the knowledge of the Son of God, [growing spiritually] to become a mature believer, reaching to the measure of the fullness of Christ [manifesting His spiritual completeness and exercising our spiritual gifts in unity]. So that we are no longer children [spiritually immature], tossed back and forth [like ships on a stormy sea] and carried about by every wind of [shifting] doctrine, by the cunning and trickery of [unscrupulous] men, by the deceitful scheming of people ready to do anything [for personal profit]. But speaking the truth in love [in all things—both our speech and our lives expressing His truth], let us grow up in all things into Him [following His example] who is the Head—Christ. From Him the whole body [the church, in all its various parts], joined and knitted firmly together by what every joint supplies, when each part is working properly, causes the body to grow and mature, building itself up in [unselfish] love.
So this I say, and solemnly affirm together with the Lord [as in His presence], that you must no longer live as the [unbelieving] Gentiles live, in the futility of their minds [and in the foolishness and emptiness of their souls], for their [moral] understanding is darkened and their reasoning is clouded; [they are] alienated and self-banished from the life of God [with no share in it; this is] because of the [willful] ignorance and spiritual blindness that is [deep-seated] within them, because of the hardness and insensitivity of their heart. And they, [the ungodly in their spiritual apathy], having become callous and unfeeling, have given themselves over [as prey] to unbridled sensuality, eagerly craving the practice of every kind of impurity [that their desires may demand]. But you did not learn Christ in this way! If in fact you have [really] heard Him and have been taught by Him, just as truth is in Jesus [revealed in His life and personified in Him], that, regarding your previous way of life, you put off your old self [completely discard your former nature], which is being corrupted through deceitful desires, and be continually renewed in the spirit of your mind [having a fresh, untarnished mental and spiritual attitude], and put on the new self [the regenerated and renewed nature], created in God’s image, [godlike] in the righteousness and holiness of the truth [living in a way that expresses to God your gratitude for your salvation].
