3 And by this we know that we have come to know him, if we ^bkeep his commandments. 4 Whoever says “I know him” but does not keep his commandments ^cis a liar, and ^cthe truth is not in him, 5 but whoever ^dkeeps his word, in him truly ^ethe love of God is perfected. ^fBy this we may know that we are in him: 6 whoever says he ^gabides in him ^hought to walk in the same way in which he walked.

The New Commandment

7 Beloved, I am writing you ⁱno new commandment, but ^jan old commandment ^kthat you had from the beginning. The old commandment is the word that you have heard. 8 At the same time, it is ^la new commandment that I am writing to you, which is true in him and in you, because^{1 m}the darkness is passing away and ⁿthe true light is already shining. 9 Whoever says he is in the light and ^ohates his brother is still in darkness. 10 Whoever loves his brother abides in the light, and in him² there is no ^pcause for stumbling. 11 But whoever hates his brother is in the darkness and ^qwalks in the darkness, and does not know where he is going, because the darkness has blinded his eyes.

Warning Concerning Antichrists

18 Children, ^ait is the last hour, and as you have heard that ^bantichrist is coming, so now ^cmany antichrists have come. ^dTherefore we know that it is the last hour. 19 ^eThey went out from us, but they were not of us; for ^fif they had been of us, they would have continued with us. But they went out, ^gthat it might become plain that they all are not of us. 20 But you have been ^hanointed by ⁱthe Holy One, and ^jyou all have knowledge.¹ 21 I write to you, not because you do not know the truth, but because you know it, and because no lie is of the truth. 22 Who is the liar but ^khe who denies that Jesus is the Christ? This is ^bthe antichrist, he who denies the Father and the Son. 23 ^lNo one who denies the Son has the Father. Whoever confesses the Son has the Father also. 24 Let ^mwhat you heard from the beginning abide in you. If what you heard from the beginning abides in you, then ⁿyou too will abide in the Son and in the Father. 25 And this is the promise that he made to us²—^oeternal life.

26 I write these things to you about ^pthose who are trying to deceive you. 27 But ^qthe anointing that you received from him abides in you, and ^ryou have no need that anyone should teach you. But as his anointing teaches you about everything, and ^sis true, and is no lie—just as it has taught you, abide in him.
