Adam Clarke on Acts 14:27

Had gathered the Church together - The Church by which they had been sent on this very important and successful mission.

They rehearsed all that God had done with them - Not what they had done themselves; but what God made them the instruments of working.

And how he had opened the door of faith - How God by his providence and grace had made a way for preaching Christ crucified among the heathen; and how the heathen had received that Gospel which, through faith in Christ Jesus, was able to save their souls.
