Ephesians 3:9

“and to make all men see what is the dispensation of the mystery which for ages hath been hid in God who created all things”.

“And to make all men see”: “And to enlighten all men” (Alf). “And to bring to light” (Rhm). See Acts 26:17. “All men”: The gospel is for all men (Mark 16:15). No Calvinistic predestination or limited atonement here. The purpose of preaching isn't to entertain or make people merely feel good, rather the purpose of preaching the gospel is to open the eyes of sinners to reality (Ephesians 1:18; Ephesians 5:7; Colossians 1:26; 2 Corinthians 4:4). “Dispensation”: “The administration (as in v. 2) was the ‘stewardship' or ‘responsibility' of how the plan was to be worked out. The focus is on how God has chosen to work out his secret purpose” (Boles p. 249). “Of the mystery”: “To make clear what is God's way of working out that hidden purpose” (TCNT). “Of bringing to light how this hidden purpose was to be put into effect” (NEB). 1 Timothy 3:16 well sums up this previously hidden truth. “Which for ages hath been hid in God”: Colossians 1:26.It was so hidden that even angels were ignorant of God's plan (1 Peter 1:10). “That the gospel of Christ was intended for the whole world is no new idea. This mystery has always been in the mind of God. The evangelization of the world is no modern project. The Jews, to whom God gave His divine revelation, narrowly concluded that salvation was for themselves, and possibly for some Gentiles who might ally themselves with them. However God opened the eyes of Paul, and others to understand the wideness of His mercy” (Erdman p. 69).

“Who created all things”: “He is not required to answer to any being, least of all to man. He had the right to choose the time for making known His purposes because He had created all things” (Caldwell p. 119). “This is no trifling matter; it connects with God's grandest operations” (Coffman p. 171). The same God who created the universe is the same God who has brought salvation to mankind. Therefore true science and true religion will always harmonize seeing that God is the author of both realms.
