Mark 16:13-16

And they went away and told it unto the rest: neither believed they them. And afterward he was manifested unto the eleven themselves as they sat at meat; and he upbraided them with their unbelief and hardness of heart, because they believed not them that had seen him after he was risen. And he said unto them, Go ye into all the world, and preach the gospel to the whole creation. He that believeth and is baptized shall be saved; but he that disbelieveth shall be condemned.
