Acts 19:15

And the evil spirit answered and said unto them Jesus I know, and Paul I know, but who are you?

It was appropriate enough that the demon himself, working through his victim, should have exposed and denounced such a wicked attempt to appropriate a precious and holy name to the promotion of evil enterprises. The lesson should be clear to all, that no man has a right merely to appropriate the name of Jesus. It may be supposed that many today are guilty of doing the same thing. Are there not thousands who say, "O yes, I am a Christian," who really have no right to such a claim? How does one become a rightful and lawful wearer of the name of Jesus? In this very chapter it is declared that men were "baptized into the name of the Lord Jesus" (Acts 19:5); and the Scriptures reveal no honorable alternative to that means of being entitled to his holy name.
