1 John 2:19

17 And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever.

18 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.

20 But ye have an unction from the Holy One, and ye know all things.

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

Do read the surrounding verses too, because the context often says more than a single verse.
