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; 16 from whom all the body, being fitted and knit together through that which every joint supplies, according to the working in measure of each individual part, makes the body increase to the building up of itself in love.
Matthew Henry's Commentary on Ephesians 4:12-16
Commentary on Ephesians 4:7-16
(Read Ephesians 4:7-16)
Unto every believer is given some gift of grace, for their mutual help. All is given as seems best to Christ to bestow upon every one. He received for them, that he might give to them, a large measure of gifts and graces; particularly the gift of the Holy Ghost. Not a mere head knowledge, or bare acknowledging Christ to be the Son of God, but such as brings trust and obedience. There is a fulness in Christ, and a measure of that fulness given in the counsel of God to every believer; but we never come to the perfect measure till we come to heaven. God's children are growing, as long as they are in this world; and the Christian's growth tends to the glory of Christ. The more a man finds himself drawn out to improve in his station, and according to his measure, all that he has received, to the spiritual good of others, he may the more certainly believe that he has the grace of sincere love and charity rooted in his heart.
