This is the message [of God’s promised revelation] which we have heard from Him and now announce to you, that God is Light [He is holy, His message is truthful, He is perfect in righteousness], and in Him there is no darkness at all [no sin, no wickedness, no imperfection].

If we say that we do not have any sin, we are deceiving ourselves and we're not being truthful to ourselves.

My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:

and the truth is not in him; bit if any man obey his word, in him truly is the love of God made perfect. By this we come to know that we are in him.

Beloved, I am not writing you any new command, but an old command which you have had from the very beginning: the old command is the word you have heard.

Any one who professes to be in the light and yet hates his brother man is still in darkness.

Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him.

From us, it is true, they went out, but they had never belonged to us; for, if they had belonged to us, they would have remained among us. They left us that it might be made clear that they do not, any of them, belong to us.

I am not writing to you because you do not know the truth, but because you do know it, and know that no lie has any connexion with the truth.

But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him.

And now, little children [i.e., dear ones], continue to live in [fellowship with] Christ, so that when He appears, we may have boldness and not have [any reason] to be ashamed in front of Him at His [second] coming.

You know that the Messiah was revealed to take away sins, and there is not any sin in him.

My Children, do not let any one mislead you. He who lives righteously is righteous--as Christ is righteous.

whosoever hateth his brother, has the disposition of a murderer: and you know that no murderer has any title to eternal life.

But if any one has this world's wealth and sees that his brother man is in need, and yet hardens his heart against him--how can such a one continue to love God?

and any inspired utterance that does not acknowledge Jesus does not come from God; it is the inspiration of the Antichrist. You have heard that it was coming, and here it is already in the world.

He who is destitute of love has never had any knowledge of God; because God is love.

No man hath seen God at any time. If we love one another, God dwelleth in us, and his love is perfected in us.

If any man confesses that "Jesus is the Son of God." God is abiding in that man, and he in God.

We love Him, because He first loved us. If any one say,

If any one say, I love God, and hate his brother, he is a liar: for he that loves not his brother whom he has seen, how can he love God whom he has not seen?

For this is [real evidence of] our love for God: [It is] obeying what He commands us to do. And obeying His commands does not cause us any grief [or, unpleasantness].

And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:

If any man see his brother sin a sin which is not unto death, he shall ask, and he shall give him life for them that sin not unto death. There is a sin unto death: I do not say that he shall pray for it.

Any kind of wrongdoing is sin; but there is sin which is not unto death.

Little children (believers, dear ones), guard yourselves from idols—[false teachings, moral compromises, and anything that would take God’s place in your heart].
