Protestants do well to memorize certain lines from the Holy Writ. We, too, can do the same. Know of the "3 Alls" and memorize this one:
Christ had just "appeared" after His death to the twelve. He "upbraided" them for their unbelief and hardness of heart and then He said to them:
"Go into all [ALL] the world and preach [ALL] the gospel to the whole [ALL] creation. He who believes and is baptized will be saved; but he who does not believe will be comndemned."
Then He went on to explain that these "signs" will accompany those whe believe, etc.
This is from Mark 16:15-16 (it is our modus operandi).
