1 John 2:3-16

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). 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. 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: 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. 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]. [John 13:34, 35] 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. The one who says he is in the Light [in consistent fellowship with Christ] and yet habitually hates (works against) his brother [in Christ] is in the darkness until now. The one who 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]. 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. 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]. 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. 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 [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. 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.
