I write to you, fathers, because you know him who is from the beginning. I write to you, young men, because you have overcome the evil one. I write to you, little children, because you know the Father.

 2:7-8 Beloved, it is not a new commandment which I am writing to you, but an old commandment which you had from the beginning, the old commandment is the word which you heard. Again, it is a new commandment which I am writing to you, a thing which is true in him and in you, because the darkness is passing away and the light is now shining.
