Keeping the New Commandment
2 My little children, I am writing these things to you in order that you may not sin. And if anyone sins, we have an advocate with the Father, Jesus Christ the righteous one, 2 and he is the propitiation for our sins, and not for ours only, but also for the sins of the whole world. 3 And by this we know that we have come to know him, if we keep his commandments. 4 The one who says “I have come to know him,” and does not keep his commandments is a liar, and the truth is not in this person. 5 But whoever keeps his word, truly in this person the love of God has been perfected. By this we know that we are in him. 6 The one who says that he resides in him ought also to walk just as that one walked.
7 Dear friends, 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. 8 Again, I am writing a new commandment to you, which is true in him and in you, because the darkness is passing away and the true light already is shining. 9 The one who says he is in the light and hates his brother is in the darkness until now. 10 The one who loves his brother resides in the light, and there is no cause for stumbling in him. 11 But the one who hates his brother is in the darkness, and walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes.
Encouragement and Assurance
12 I am writing to you, little children, because your sins have been forgiven you on account of his name. 13 I am writing to you, fathers, because you have known the One who is from the beginning. I am writing to you, young men, because you have conquered the evil one. 14 I have written to you, children, because you have known the Father. I have written to you, fathers, because you have known the One who is from the beginning. I have written to you, young men, because you are strong, and the word of God resides in you, and you have conquered the evil one.
Do Not Love the World
15 Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him, 16 because everything that is in the world—the desire of the flesh and the desire of the eyes and the arrogance of material possessions—is not from the Father, but is from the world. 17 And the world is passing away, and its desire, but the one who does the will of God remains forever.
