Ephesians 4:13
KJV
Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ:
NIV
until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure [omit] of the fullness of Christ.
In the KJV, this verse is prophetic, pointing to the future when believers will “all come in the unity of the faith” as the body of Christ in its fulness: “a perfect man,” with every member in perfect agreement at the time of our glorification (cf. 1 Cor. 15:47–52). Modern versions shift the promise of this future event into a present, works-oriented process. “Until we all reach unity in the faith… attaining to…” implies an ecumenical end goal that is to be achieved by works here on earth.
