Chapter 1
1That which was from the beginning, which we have heard, which we have seen with our own eyes, which we have gazed upon and touched with our own hands—this is the Word of life. 2And this is the life that was revealed; we have seen it and testified to it, and we proclaim to you the eternal life that was with the Father and was revealed to us. 3We proclaim to you what we have seen and heard, so that you also may have fellowship with us. And this fellowship of ours is with the Father and with His Son, Jesus Christ. 4We write these things so that our joy may be complete. 5And this is the message we have heard from Him and announce to you: God is light, and in Him there is no darkness at all. 6If we say we have fellowship with Him yet walk in the darkness, we lie and do not practice the truth. 7But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus His Son cleanses us from all sin. 8If we say we have no sin, we deceive ourselves, and the truth is not in us. 9If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. 10If we say we have not sinned, we make Him out to be a liar, and His word is not in us.
Chapter 2
1My 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. 2He Himself is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world. 3By this we can be sure that we have come to know Him: if we keep His commandments. 4If anyone says, “I know Him,” but does not keep His commandments, he is a liar, and the truth is not in him. 5But if anyone keeps His word, the love of God has been truly perfected in him. By this we know that we are in Him: 6Whoever claims to abide in Him must walk as Jesus walked. 7Beloved, I am not writing to you a new commandment, but an old one, which you have had from the beginning. This commandment is the message you have heard. 8Then again, I am also writing to 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. 9If anyone claims to be in the light but hates his brother, he is still in the darkness. 10Whoever loves his brother remains in the light, and there is no cause of stumbling in him. 11But 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. 12I am writing to you, little children, because your sins have been forgiven through His name. 13I 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. 14I 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. 15Do not love the world or anything in the world. If anyone loves the world, the love of the Father is not in him. 16For 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. 17The world is passing away, along with its desires; but whoever does the will of God remains forever.
