1 John 2:1-17New Revised Standard Version (NRSV)
Christ Our Advocate
2 My little children, I am writing these things to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous; 2 and he is the atoning sacrifice for our sins, and not for ours only but also for the sins of the whole world.
3 Now by this we may be sure that we know him, if we obey his commandments. 4 Whoever says, “I have come to know him,” but does not obey his commandments, is a liar, and in such a person the truth does not exist; 5 but whoever obeys his word, truly in this person the love of God has reached perfection. By this we may be sure that we are in him: 6 whoever says, “I abide in him,” ought to walk just as he walked.
A New Commandment
7 Beloved, I am writing you no new commandment, but an old commandment that you have had from the beginning; the old commandment is the word that you have heard. 8 Yet I am writing you a new commandment that is true in him and in you, because[a] the darkness is passing away and the true light is already shining. 9 Whoever says, “I am in the light,” while hating a brother or sister,[b] is still in the darkness. 10 Whoever loves a brother or sister[c] lives in the light, and in such a person[d] there is no cause for stumbling. 11 But whoever hates another believer[e] is in the darkness, walks in the darkness, and does not know the way to go, because the darkness has brought on blindness.
12 I am writing to you, little children,
15 Do not love the world or the things in the world. The love of the Father is not in those who love the world; 16 for all that is in the world—the desire of the flesh, the desire of the eyes, the pride in riches—comes not from the Father but from the world. 17 And the world and its desire[f] are passing away, but those who do the will of God live forever.
