1 John 2:
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 word which you have heard. 8[c]On the other hand, 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 is already shining. 9The one who says that he is in the Light and yet hates his brother or sister is in the darkness until now. 10The one who loves his brother and sister remains in the Light, and there is nothing in him to cause stumbling. 11But the one who hates his brother or sister is in the darkness and walks in the darkness, and 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 you on account of His name. 13I am writing to you, fathers, because you know Him who has been 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 has been from the beginning. I have written to you, young men, because you are strong, and the word of God remains in you, and you have overcome the evil one.
