If we say that we have fellowship with Him and yet walk in the darkness, we lie and do not practice the truth;

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

The one who says, “I have come to know Him,” and does not keep His commandments, is a liar, and the truth is not in him;

I have not written to you because you do not know the truth, but because you do know it, and because no lie is of the truth.

Little children, let’s not love with word or with tongue, but in deed and truth.

We will know by this that we are of the truth, and will set our heart at ease before Him,

We are from God. The one who knows God listens to us; the one who is not from God does not listen to us. By this we know the spirit of truth and the spirit of error.

This is the One who came by water and blood, Jesus Christ; not with the water only, but with the water and with the blood. It is the Spirit who testifies, because the Spirit is the truth.
