Acts 14:27

When they arrived the entire congregation gathered together while Paul and Barnabas related all that had happened. Here is Bible authority for the congregation to come together and hear about the preaching efforts of various men. "All the things that God had done with them" God had been "with" the preachers, He had spoken and worked miracles through them. "And how He had opened. door of faith to the Gentiles" Paul often will speak of "open doors" (1 Corinthians 16:9; 2 Corinthians 2:12; Colossians 4:3). Such doors are great opportunities to speak the gospel and teach others. Notice the "door" that one must walk through does not go through the Law of Moses, but rather through faith. And faith only comes one way, through listening to and embracing what the word of God says (Romans 10:17). In addition, notice how God is given the credit. Yes, Paul and Barnabas had preached, but the message was God's message (1 Corinthians 3:6 ff).
