1 John 2:18

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.

1 John 2:18 In-Context

16 because all the things of the world - the desires of the old nature, the desires of the eyes, and the pretensions of life - are not from the Father but from the world.
17 And the world is passing away, along with its desires. But whoever does God's will remains forever.
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.
