"John said unto Him, Master, we saw one casting out devils in Thy Name: and we forbade him, because he followed not us. But Jesus said, Forbid him not: for there is no man which 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. For whosoever shall give you a cup of water to drink, because ye are Christ's, verily I say unto you, he shall in no wise lose his reward. And whosoever shall cause one of these little ones that believe on Me to stumble, it were better for him if a great millstone were hanged about his neck, and he were cast into the sea. And if thy hand cause thee to stumble, cut it off: it is good for thee to enter into life maimed, rather than having thy two hands to go into hell, into the unquenchable fire. And if thy foot cause thee to stumble, cut it off: it is good for thee to enter into life halt, rather than having thy two feet to be cast into hell. And if thine eye cause thee to stumble, cast it out: it is good for thee to enter into the kingdom of God with one eye, rather than having two eyes to be cast into hell; where their worm dieth not, and the fire is not quenched. For every one shall be salted with fire. Salt is good: but if the salt have lost its saltness, wherewith will ye season it? Have salt in yourselves, and be at peace one with another."--MARK ix. 38-50 (R.V.).
When Jesus spoke of the blessedness of receiving in His name even a little child, the conscience of St. John became uneasy. They had seen one casting out devils in that name, and had forbidden him, "because he followeth not us." The spirit of partizanship which these words betray is somewhat softer in St. Luke, but it exists. He reports "because he followeth not (Jesus) with us."
The behaviour of the disciples all through this period is unsatisfactory. From the time when Peter contradicted and rebuked Jesus, down to their final desertion, there is weakness at every turn. And this is a curious example of it, that immediately after having failed themselves,(12) they should rebuke another for doing what their Master had once declared could not possibly be an evil work. If Satan cast out Satan his house was divided against itself: if the finger of God was there no doubt the kingdom of God was come unto them.
