1John 2:18-19 (NIV) 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. 19 They went out
from us, but they did not really belong to us.
For if they had belonged to us, they would have
remained with us; but their going showed that
none of them belonged to us.
