Ephesians 3:21

unto Him be glory in the Church by Jesus Christ throughout all ages, world without end. Amen.

As in other instances, Romans 11:33; Galatians 1:5; 1 Timothy 1:17, the apostle closes this section of his letter with a doxology. He addresses himself to God, who is able to do beyond all, exceeding abundantly above what we ask or think. The program which Paul has outlined is of a nature to make the average Christian hesitate, so much does it embrace. But his reference to the almighty power of the gracious God quiets all doubts. He is able, according to the power which is active in us, of whose greatness we have indisputable evidence, to do and perform in our behalf far more than we can even think of asking for, far more than our feeble understanding can grasp. "I can do all things through Christ, which strengtheneth me," Philippians 4:13. The miracles which we have experienced in our own hearts and lives in our state of being Christians, since our conversion, are a guarantee to us that God will be able to carry out all His plans and intentions with regard to our salvation and sanctification. The apostle's prayer will therefore surely not be in vain. And so we join with him in saying: Unto Him be the glory in the Church and in Christ Jesus to all generations of the eternity of eternities. In the Church His glory shall be proclaimed; the entire Church should confess that the praise is not due to men, neither to the apostles and preachers nor to the individual members, but to God alone; therefore His glory shall be forever extolled. And our prayer of thanksgiving rises to the throne of God in Christ Jesus, our Redeemer and Mediator, forever and ever. Here we make but a feeble beginning with our psalms and hymns of praise; the real chorus will sound forth in a mighty, never-ending anthem when we shall join the choirs of the blessed angels and sing His praises, world without end. Amen, that is, yea, yea, it shall be so.

Summary

The apostle praises the grace which was given him in his ministry to the Gentiles, since its object was to collect the chosen children of God in a Church which was to be the pride and delight of God and the holy angels; he prays that the Christians may grow in faith and love and understand ever better the general character and wide extent of the Church of Christ.
