1My little children (believers, dear ones), I am writing you these things so that you will not sin and violate God’s law. And if anyone sins, we have an Advocate [who will intercede for us] with the Father: Jesus Christ the righteous [the upright, the just One, who conforms to the Father’s will in every way—purpose, thought, and action].

2And He [that same Jesus] is the propitiation for our sins [the atoning sacrifice that holds back the wrath of God that would otherwise be directed at us because of our sinful nature—our worldliness, our lifestyle]; and not for ours alone, but also for [the sins of all believers throughout] the whole world.

3And this is how we know [daily, by experience] that we have come to know Him [to understand Him and be more deeply acquainted with Him]: if we habitually keep [focused on His precepts and obey] His commandments (teachings).

4Whoever says, “I have come to know Him,” but does not habitually keep [focused on His precepts and obey] His commandments (teachings), is a liar, and the truth [of the divine word] is not in him.

5But whoever habitually keeps His word and obeys His precepts [and treasures His message in its entirety], in him the love of God has truly been perfected [it is completed and has reached maturity]. By this we know [for certain] that we are in Him:

6whoever says he lives in Christ [that is, whoever says he has accepted Him as God and Savior] ought [as a moral obligation] to walk and conduct himself just as He walked and conducted Himself.

7Beloved, I am not writing a new commandment to you, but an old commandment which you have had from the beginning; the old commandment is the message which you have heard [before from us].

8On the other hand, I am writing a new commandment to you, which is true and realized in Christ and in you, because the darkness [of moral blindness] is clearing away and the true Light [the revelation of God in Christ] is already shining.

9The one who says he is in the Light [in consistent fellowship with Christ] and yet This focuses more on the self-centered, hateful actions (not the emotion) of someone who habitually cultivates an obstructionistic attitude, and ignores the command to act in a way that expresses unselfish Christian love (see note v 10).habitually hates (works against) his brother [in Christ] is in the darkness until now.

10The one who The key to understanding this and other statements about love is to know that this love (the Greek word agape) is not so much a matter of emotion as it is of doing things for the benefit of another person, that is, having an unselfish concern for another and a willingness to seek the best for another.loves and unselfishly seeks the best for his [believing] brother lives in the Light, and in him there is no occasion for stumbling or offense [he does not hurt the cause of Christ or lead others to sin].

11But the one who habitually hates (works against) his brother [in Christ] is in [spiritual] darkness and is walking in the darkness, and does not know where he is going because the darkness has blinded his eyes.

12I am writing to you, little children (believers, dear ones), because your sins have been forgiven for His name’s sake [you have been pardoned and released from spiritual debt through His name because you have confessed His name, believing in Him as Savior].

13I am writing to you, fathers [those believers who are spiritually mature], because you know Him who has existed from the beginning. I am writing to you, young men [those believers who are growing in spiritual maturity], because you have been victorious and have overcome the evil one. I have written to you, children [those who are new believers, those spiritually immature], because you have come to know the Father.

14I have written to you, fathers, because you know Him who has existed from the beginning. I have written to you, young men, because you are strong and vigorous, and the word of God remains [always] in you, and you have been victorious over the evil one [by accepting Jesus as Savior].

15Do not love the world [of sin that opposes God and His precepts], nor the things that are in the world. If anyone loves the world, the love of the Father is not in him.

16For all that is in the world—the lust and sensual craving of the flesh and the lust and longing of the eyes and the boastful pride of life [pretentious confidence in one’s resources or in the stability of earthly things]—these do not come from the Father, but are from the world.

17The world is passing away, and with it its lusts [the shameful pursuits and ungodly longings]; but the one who does the will of God and carries out His purposes lives forever.

18Children, it is the last hour [the end of this age]; and just as you heard that the antichrist is coming [the one who will oppose Christ and attempt to replace Him], even now many antichrists (false teachers) have appeared, which confirms our belief that it is the last hour.

19They went out from us [seeming at first to be Christians], but they were not really of us [because they were not truly born again and spiritually transformed]; for if they had been of us, they would have remained with us; but they went out [teaching false doctrine], so that it would be clearly shown that none of them are of us.

20But you have an anointing from the Holy One [you have been set apart, specially gifted and prepared by the Holy Spirit], and all of you know [the truth because He teaches us, illuminates our minds, and guards us from error].

21I have not written to you because you do not know the truth, but because you do know it, and because no lie [nothing false, no deception] is of the truth.

22Who is the liar but the one who denies that Jesus is the Christ (the Messiah, the Anointed)? This is the antichrist [the enemy and antagonist of Christ], the one who denies and consistently refuses to acknowledge the Father and the Son.

23Whoever denies and repudiates the Son does not have the Father; the one who confesses and acknowledges the Son has the Father also.

24As for you, let that remain in you [keeping in your hearts that message of salvation] which you heard from the beginning. If what you heard from the beginning remains in you, you too will remain in the Son and in the Father [forever].

25This is the promise which He Himself promised us—eternal life.

26These things I have written to you with reference to those who are trying to deceive you [seducing you and leading you away from the truth and sound doctrine].

27As for you, the anointing [the special gift, the preparation] which you received from Him remains [permanently] in you, and you have no need for anyone to teach you. But just as His anointing teaches you [giving you insight through the presence of the Holy Spirit] about all things, and is true and is not a lie, and just as His anointing has taught you, Or you are abiding.you must remain in Him [being rooted in Him, knit to Him].

28Now, little children (believers, dear ones), remain in Him [with unwavering faith], so that when He appears [at His return], we may have [perfect] confidence and not be ashamed and shrink away from Him at His coming.

29If you know that He is absolutely righteous, you know [for certain] that everyone who practices righteousness [doing what is right and conforming to God’s will] has been born of Him.
