"Little children,it is the last time:and as ye have heard that antichrist shall come,even now are there many antichrists;whereby we know that it is the last time.
They went out from us,but they were not of us;for if they had been of us,they would no doubt have continued with us:but they went out, that they might be made manifest that they were not all of us.
But ye have an unction from the Holy One,and ye know all things."
1 John 2:18-20
