Mark 16:15, 20

And He said to them, “Go into all the world and preach the gospel to all creation.

And they went out and preached everywhere, while the Lord worked with them, and confirmed the word by the signs that followed.] [ A nd they promptly reported all these instructions to Peter and his companions. And after that, Jesus Himself sent out through them from east to west the sacred and imperishable proclamation of eternal salvation.]
