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. 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. 1 John 2:18-19.
“The universal witness of the New Testament is that apostasy if persisted in not only damns but shows that salvation was never real in the first place. The New Testament reveals how close one may come to the kingdom – tasting, touching, perceiving, understanding. And it also shows that to come this far and reject the truth is unforgivable.” – D.A. Carson.
