Acts 10. Cornelius wasn't a Jew or a Jewish convert, but he was a Godly man living according to the light he had and pursuing more. Cornelius was knocking and Jesus was slowly, progressively opening the door. Peter wasn't ready for just how wide God was going to throw open the doors to outsiders all over the world. The Word came to the Jews and the Jews rejected him, and their rejection would throw open the Gospel floodgates to the whole world.
