But if we walk in the light as he himself is in the light, we have fellowship with one another and the blood of Jesus his Son cleanses us from all sin.

We know that we have crossed over from death to life because we love our fellow Christians. The one who does not love remains in death.

(The one who believes in the Son of God has the testimony in himself; the one who does not believe God has made him a liar, because he has not believed in the testimony that God has testified concerning his Son.)

(My little children, I am writing these things to you so that you may not sin.) But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous One,

The one who practices sin is of the devil, because the devil has been sinning from the beginning. For this purpose the Son of God was revealed: to destroy the works of the devil.

By this the children of God and the children of the devil are revealed: Everyone who does not practice righteousness – the one who does not love his fellow Christian – is not of God.

There is no fear in love, but perfect love drives out fear, because fear has to do with punishment. The one who fears punishment has not been perfected in love.

The one who says “I have come to know God” and yet does not keep his commandments is a liar, and the truth is not in such a person.

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

By this the love of God is revealed in us: that God has sent his one and only Son into the world so that we may live through him.

I have written to you, children, that you have known the Father. I have written to you, fathers, that you have known him who has been from the beginning. I have written to you, young people, that you are strong, and the word of God resides in you, and you have conquered the evil one.

And we have come to know and to believe the love that God has in us. God is love, and the one who resides in love resides in God, and God resides in him.

If anyone says “I love God” and yet hates his fellow Christian, he is a liar, because the one who does not love his fellow Christian whom he has seen cannot love God whom he has not seen.

And we know that the Son of God has come and has given us insight to know him who is true, and we are in him who is true, in his Son Jesus Christ. This one is the true God and eternal life.

Everyone who resides in him does not sin; everyone who sins has neither seen him nor known him.

Everyone who denies the Son does not have the Father either. The person who confesses the Son has the Father also.

For there are three that testify,

Dear friends, 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 that you have already heard.

Everyone who has been fathered by God does not practice sin, because God’s seed resides in him, and thus he is not able to sin, because he has been fathered by God.

the Spirit and the water and the blood, and these three are in agreement.
