“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.”
King James Version (KJV)
9:39 Jesus said - Christ here gives us a lovely example of candour and moderation. He was willing to put the best construction on doubtful cases, and to treat as friends those who were not avowed enemies. Perhaps in this instance it was a means of conquering the remainder of prejudice, and perfecting what was wanting in the faith and obedience of these persons. Forbid him not - Neither directly nor indirectly discourage or hinder any man who brings sinners from the power of Satan to God, because he followeth not us, in opinions, modes of worship, or any thing else which does not affect the essence of religion.
Mr 9:39 Forbid him not. He neither praises nor blames him for following an independent course, and not working with his disciples. He simply declares that he must not be forbidden, and that those who work the same kind of work that we do should be regarded not as enemies, but allies. Thousands, in every period of church history, have spent their lives in copying John's mistake. They have labored to stop every man who will not work for Christ in their way from working for Christ at all (Ryle).
