10. Whoever loves his brother [believer] abides (lives) in the Light, and in It or in him there is no occasion for stumbling or cause for error or sin.
11. But he who hates (detests, despises) his brother [in Christ] is in darkness and walking (living) in the dark; he is straying and does not perceive or know where he is going, because the darkness has blinded his eyes.
12. I am writing to you, little children, because for His name's sake your sins are forgiven [pardoned through His name and on account of confessing His name].
13. I am writing to you, fathers, because you have come to know (recognize, be aware of, and understand) Him Who [has existed] from the beginning. I am writing to you, young men, because you have been victorious over the wicked [one]. I write to you, boys (lads), because you have come to know (recognize and be aware) of the Father.
14. I write to you, fathers, because you have come to know (recognize, be conscious of, and understand) Him Who [has existed] from the beginning. I write to you, young men, because you are strong and vigorous, and the Word of God is [always] abiding in you (in your hearts), and you have been victorious over the wicked one.
15. Do not love or cherish the world or the things that are in the world. If anyone loves the world, love for the Father is not in him.
16. For all that is in the world–the lust of the flesh [craving for sensual gratification] and the lust of the eyes [greedy longings of the mind] and the pride of life [assurance in one's own resources or in the stability of earthly things]–these do not come from the Father but are from the world [itself].
17. And the world passes away and disappears, and with it the forbidden cravings (the passionate desires, the lust) of it; but he who does the will of God and carries out His purposes in his life abides (remains) forever.
18. Boys (lads), it is the last time (hour, the end of this age). And as you have heard that the antichrist [he who will oppose Christ in the guise of Christ] is coming, even now many antichrists have arisen, which confirms our belief that it is the final (the end) time.
19. They went out from our number, but they did not [really] belong to us; for if they had been of us, they would have remained with us. But [they withdrew] that it might be plain that they all are not of us.
20. But you have been anointed by [you hold a sacred appointment from, you have been given an unction from] the Holy One, and you all know [the Truth] or you know all things.
21. I write to you not because you are ignorant and do not perceive and know the Truth, but because you do perceive and know it, and [know positively] that nothing false (no deception, no lie) is of the Truth.
22. Who is [such a] liar as he who denies that Jesus is the Christ (the Messiah)? He is the antichrist (the antagonist of Christ), who [habitually] denies and refuses to acknowledge the Father and the Son.
