Charles Spurgeon Commentary Mark 9:39-40

"But Jesus said, Forbid him not: for there is no man who shall do a mighty work in my name, and be able quickly to speak evil of me. For he that is not against us is for us." — Mark 9:39-40 (ASV)

But Jesus said, Forbid him not: for there is no man which shall do a miracle in my name, that can lightly speak evil of me. For he that is not against us is on our part.

Thus the Master had to talk to his poor disciples after having conversed with Moses and Elias. Again, I say, what a come-down it was from fellowship with the great law-giver of Israel, and with the mighty prophet of fire, to talk with these childish men who had fallen out among themselves, and fallen out with other people! O blessed Master, we may gladly hope that you will commune with us as you communed with them! We may also trust that some poor sinner, even though the devil may be in him, may catch your eye of pity and love, and that you may heal him.
