“My little children, I am writing these things to you so that you will not sin. But if anyone does sin, we have an advocate before the Father—Jesus Christ, the Righteous One. He Himself is the atoning sacrifice for our sins, and not for ours alone, but also for the sins of the whole world.

By this we can be sure that we have come to know Him: if we keep His commandments. If anyone says, “I know Him,” but does not keep His commandments, he is a liar, and the truth is not in him. But if anyone keeps His word, the love of God has been truly perfected in him. By this we know that we are in Him: Whoever claims to abide in Him must walk as Jesus walked.
Beloved, I am not writing you a new commandment, but an old one, which you have had from the beginning. This commandment is the message you have heard. Then again, I am also writing you a new commandment, which is true in Him and also in you. For the darkness is fading and the true light is already shining.

If anyone claims to be in the light but hates his brother, he is still in the darkness. Whoever loves his brother remains in the light, and there is no cause of stumbling in him. But whoever hates his brother is in the darkness and walks in the darkness. He does not know where he is going, because the darkness has blinded his eyes.

I am writing to you, little children, because your sins have been forgiven through His name.

I am writing to you, fathers, because you know Him who is from the beginning.

I am writing to you, young men, because you have overcome the evil one.

I have written to you, children, because you know the Father.

I have written to you, fathers, because you know Him who is from the beginning.

I have written to you, young men, because you are strong, and the word of God abides in you, and you have overcome the evil one.
Do not love the world or anything 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 desires of the flesh, the desires of the eyes, and the pride of life—is not from the Father but from the world. The world is passing away along with its desires, but whoever does the will of God remains forever.” I John 2:1-17
