1 John 4:3

Verse 3. And every spirit that confesseth not.

The crucial test being given, and the spirit tried by this test refusing to confess that Jesus Christ is come in the flesh, you may know, beyond question, is not of God, but is of antichrist. It was not only foretold that antichrist would come, but be it known, such are already in the world. As it was in he days of John, so it is now in our age. Some of these false teachers claim to be inspired. They did then, and they do now.
