but whoever follows His word, in him the love of God has truly been perfected. By this we know that we are in Him:
the one who says that he remains in Him ought, himself also, walk just as He walked.
Beloved, 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.
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.
The one who says that he is in the Light and yet
hates his brother or sister
is in the darkness until now.
The one who loves his brother and sister
remains in the Light, and there is nothing in him to cause stumbling.
But 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.
I am writing to you, little children, because your sins have been forgiven you on account of His name.
I 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.
