³ And 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). ⁴ Whoever 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. ⁵ But 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: ⁶ whoever 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.

⁷ Beloved, 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].^{(A) 8} On 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. ⁹ The one who says he is in the Light [in consistent fellowship with Christ] and yet ^[a]habitually hates (works against) his brother [in Christ] is in the darkness until now. ¹⁰ The one who ^[b]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]. ¹¹ But 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.

¹² I 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]. ¹³ I 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. ¹⁴ I 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].

Do Not Love the World

¹⁵ Do 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. ¹⁶ For 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. ¹⁷ The 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.

¹⁸ Children, 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. ¹⁹ They 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. ²⁰ But 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]. ²¹ I 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. ²² Who 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. ²³ Whoever denies and repudiates the Son does not have the Father; the one who confesses and acknowledges the Son has the Father also. ²⁴ As 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].

The Promise Is Eternal Life

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

²⁶ These 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]. ²⁷ As 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, ^[c]you must remain in Him [being rooted in Him, knit to Him].
