“But speaking the truth in love, may grow up into him in all things, which is the head, even Christ:”
King James Version (KJV)
4:15 Into him - Into his image and Spirit, and into a full union with him.
Eph 4:15 Speaking the truth in love. Truth is never to give way to false doctrine, but it must be spoken in love. Some cling to the truth tenaciously, but forget to speak it in love. Grow up into him in all things. This continues the characteristics of those "who are no longer children" (Eph 4:14). In all their growth there should be a growth of Christ's traits, a growth into his likeness.
