My little children, these things I write to you, so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous.

And He Himself is the propitiation for our sins, and not for ours only but also for the whole world.

Now by this we know that we know Him, if we keep His commandments.

He who says, “I know Him,” and does not keep His commandments, is a liar, and the truth is not in him.

But whoever keeps His word, truly the love of God is perfected in him. By this we know that we are in Him.

He who says he abides in Him ought himself also to walk just as He walked.

He who says he is in the light, and hates his brother, is in darkness until now.

He who loves his brother abides in the light, and there is no cause for stumbling in him.

But he who hates his brother is in darkness and walks in darkness, and does not know where he is going, because the darkness has blinded his eyes.
