1 John 2:19

Verse 19. They went out from us.

The meaning here is clear. All these antichrists are simply apostates. They sprang up from the Church of Christ; and yet, while this is true, they were not of us. They were not genuine converts; they were simply wolves in sheep's clothing. Their profession of faith in Christ was a mere pretense, for had they the whole-hearted faith in the Son of God, so requisite to citizenship in his kingdom, they would have continued humble, loving disciples. As it is, their going out from among us, and their bitter opposition to the doctrine of Christ, is an exhibition of the fact that they never were really and truly converted. They only made a pretense of conversion, the better to enable them to carry out their own designs.
