Mar 9:39 Forbid him not: for there is no man which shall do a miracle in my name...

Mar 9:39 Forbid him not: for there is no man which shall do a miracle in my name, that can lightly speak evil of me.
Alternative: Don't stop him: because no one who produces power in my name has the power to say a bad word about me quickly.

In the alternative above, I preserve the play on words in the original Greek. The point that Christ makes is that the use of certain powers also limits how that power can be used. This may be an important note in discussing the rules of the spiritual world.

This verse also suggests interesting ideas concerning the connection between words and power. Using Christ's name gives people power. This power comes from belief in the concept of spiritual power, which makes everything possible (Mar 9:25). However, no one can believe and not believe at the same time. So the power of faith demands consistency. As Christ says, we cannot quickly change the way we think.
