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 remains in you, and you have overcome the evil one.

 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.
