1 John 2:18-21

18 Little children, it is the last hour, and as ye have heard that the antichrist comes, likewise there are also beginning to be many antichrists, by which we know that it is the last time.

19 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 this happened that it might be made manifest that they were not all of us.

20 But ye have the anointing of the Holy One, and ye know all things.

21 I have not written unto you as if ye ignore the truth, but as unto those that know it, and that no lie is of the truth.
