1 John 2:3-11

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 habitually hates (works against) his brother [in Christ] is in the darkness until now.

10The 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].

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.
