For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to everyone that believeth; to the Jew first, and also to the Greek. Romans 1:16

And he said unto them, Go ye into all the world, and preach the gospel to every creature. Anyone who believes and is baptized will be saved. But anyone who refuses to believe will be condemned. And these signs will accompany those who believe: in my name they will cast out demons; they will speak in new tongues; they will pick up snakes with their hands; and when they drink deadly poison, it will not hurt them at all; they will place their hands on sick people, and they will get well. Mark 16:17-19
