The Open Door

"On their arrival they assembled the church and gave an account of all that God had done with them, and how he had opened the door of faith to the gentiles." (Acts 14: 27)

Apostolic work is God's work. God opens the door.

"I have opened a door before you which no man will be able to close." (Revelation 3:8)

God opened the door for Paul and Barnabas to evangelize the gentiles. The door opened by God will remain open come what may.
