If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:

If we say that we have no sin, we deceive ourselves, and the truth is not in us.

If we say openly that we have done wrong, he is upright and true to his word, giving us forgiveness of sins and making us clean from all evil.

If we say that we have not sinned, we make him a liar, and his word is not in us.

He that says, I know him, and does not keep his commandments, is a liar, and the truth is not in him;

He that says he abides in him ought, even as he walked, himself also so to walk.

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

Who is false but he who says that Jesus is not the Christ? He is the Antichrist who has no belief in the Father or the Son.

And now, little children, abide, I say, in Him; that, when He shall appear, we may have confidence, and may not be ashamed before Him at his coming.

When our heart says that we have done wrong; because God is greater than our heart, and has knowledge of all things.

My loved ones, if our heart does not say that we have done wrong, we have no fear before him;

By this you may have knowledge of the Spirit of God: every spirit which says that Jesus Christ has come in the flesh is of God:

And every spirit which does not say this is not from God: this is the spirit of Antichrist, of which you have had word; and it is in the world even now.

They are from the world. Therefore what they say is from the world, and the world listens to them.

Everyone who says openly that Jesus is the Son of God, has God in him and is in God.

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

If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, how can he love God whom he hath not seen?

For whoever [Note: The Greek says "whatever"] is [spiritually] conceived [and eventually born] by God will overcome [the evil influence of] the world. And this is [how] that victory can be gained over the world: [It is through] our faith [in God].

The person who [sincerely] believes in God's Son has the evidence [of it] within his heart, [confirming God's testimony]. The person who does not believe God [i.e., what He says about Jesus], accuses Him of lying, because he has not accepted the [irrefutable] testimony of God concerning [the identity and mission of] His Son.

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.

There is a sin unto death: I do not say that he shall pray for that. All unrighteousness is sin: but there is a sin not unto death.
