Ephesians 4:12-15

12 for the perfecting of the saints, to the work of serving, to the building up of the body of Christ;  13 until we all attain to the unity of the faith, and of the knowledge of the Son of God, to a full grown man, to the measure of the stature of the fullness of Christ;  14 that we may no longer be children, tossed back and forth and carried about with every wind of doctrine, by the trickery of men, in craftiness, after the wiles of error;  15 but speaking truth in love, we may grow up in all things into him, who is the head, Christ;
