Little children, it is the last hour; and as you have heard that the Antichrist is coming, even now many antichrists have come, by which we know that it is the last hour. 19 They went out from us, but they were not of us; for if they had been of us, they would have continued with us; but they went out that they might be made manifest, that none of them were of us.
20 But you have an anointing from the Holy One, and you know all things. 21 I have not written to you because you do not know the truth, but because you know it, and that no lie is of the truth.
22 Who is a liar but he who denies that Jesus is the Christ? He is antichrist who denies the Father and the Son. 23 Whoever denies the Son does not have the Father either; he who acknowledges the Son has the Father also.
24 Therefore let that abide in you which you heard from the beginning. If what you heard from the beginning abides in you, you also will abide in the Son and in the Father. 25 And this is the promise that He has promised us—eternal life.
26 These things I have written to you concerning those who try to deceive you. 27 But the anointing which you have received from Him abides in you, and you do not need that anyone teach you; but as the same anointing teaches you concerning all things, and is true, and is not a lie, and just as it has taught you, you will abide in Him.
28 And now, little children, abide in Him, that when He appears, we may have confidence and not be ashamed before Him at His coming. 29 If you know that He is righteous, you know that everyone who practices righteousness is born of Him.
