Twice Paul was halted. He tried to go somewhere, but God didn’t open the door.
Paul and his companions traveled throughout the region of Phrygia and Galatia, HAVING BEEN KEPT BY THE HOLY SPIRIT from preaching the word in the province of Asia. When they came to the border of Mysia, they tried to enter Bithynia, BUT THE SPIRIT OF JESUS WOULD NOT ALLOW THEM TO. During the night Paul had a vision of a man of Macedonia standing and begging him, “Come over to Macedonia and help us.” — Acts 16:6,7,9 NIV.
Sometimes, the doors don’t open for years and years and years.
Maybe the reason why the door is not opening is because it’s never going to open. Try another door.
