1 John 2:18

18 Dear children, this is the last hour; and as you have heard that the antichrist is coming, even now many antichrists have come. This is how we know it is the last hour.

1 John 2:28

28 And now, dear children, continue in him, so that when he appears we may be confident and unashamed before him at his coming.

1 John 3:2

2 Dear friends, now we are children of God, and what we will be has not yet been made known. But we know that when Christ appears, we shall be like him, for we shall see him as he is.

1 John 4:3

3 but every spirit that does not acknowledge Jesus is not from God. This is the spirit of the antichrist, which you have heard is coming and even now is already in the world.
