The Shepherd of Hermas

How, sir, said I, can these things be? For both these things which you have spoken of are impossible. Even, said he, as these are impossible, so also are the earthly spirits without power and feeble.

Take now the power which comes from above. The hail is a very little grain, and when it falls on man’s head, how it hurts! Or, again, take a drop which falls on the ground from the roof, and makes a hole in stone.

You see, then, that the smallest things which come from above and fall on the earth have great power; so also the Divine Spirit which comes from above is powerful. Have faith, then, in this Spirit, but refrain from the other.
