“And He gave some as apostles, and some as prophets, and some as evangelists, and some as pastors and teachers, for the quipping of the saints for the work of services, to the building up of the body of Christ; until we all attain to the unity of the faith, and of the knowledge of the Son of God, to a mature man, to the measure of the stature which belongs to the fullness of Christ. As a result, we are no longer to be children, tossed here and there by waves and carried about by every wind of doctrine, by the trickery of men, by craftiness in deceitful scheming; but speaking the truth in love, we are to grow up in all aspects into Him who is the head, even Christ, from whom the whole body, being fitted and held together by what every joint supplies, according to the proper working of each individual part, causes the growth of the body for the building up of itself in love.”
The emphasis of these verses is the building up of the body—not on spiritual gifts, as some like to emphasize.
God’s Plan: To build up the body: 1) Unity in Faith; 2) Unity in knowledge
A mature person can discern right and wrong, and thereby practice God’s will.
Ephesians 4:17-19—there is only one head--Christ. We either have a head or we do not have a head.
