1 John 2:18-21

18 Children, this is the Last Hour. You have heard that an Anti-Messiah is coming; and in fact, many anti-Messiahs have arisen now - which is how we know that this is the Last Hour.

19 They went out from us, but they weren't part of us; for had they been part of us, they would have remained with us.

20 But you have received the Messiah's anointing from HaKadosh, and you know all this.

21 It is not because you don't know the truth that I have written to you, but because you do know it, and because no lie has its origin in the truth.
