“Unto him be glory in the church by Christ Jesus throughout all ages, world without end. Amen.”
King James Version (KJV)
3:21 In the church - On earth and in heaven.
Eph 3:21 Unto him [be] glory in the church by Jesus Christ. Let the church in all ages manifest his glory by its light. Throughout all ages. Literally, "Unto all the generations of the age of ages". The idea is, through the endless succession of ages, or through all time.
