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.

As for you, what you have heard from the beginning must remain in you. If what you heard from the beginning remains in you, you also will remain in the Son and in the Father.

The one who says he is in the light but still hates his fellow Christian is still in the darkness.

The one who loves his fellow Christian resides in the light, and there is no cause for stumbling in him.

We know that we are from God, and the whole world lies in the power of the evil one.

Jesus Christ is the one who came by water and blood – not by the water only, but by the water and the blood. And the Spirit is the one who testifies, because the Spirit is the truth.

If we say we have fellowship with him and yet keep on walking in the darkness, we are lying and not practicing the truth.

Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him,

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.

You are from God, little children, and have conquered them, because the one who is in you is greater than the one who is in the world.

If anyone confesses that Jesus is the Son of God, God resides in him and he in God.

And this is the testimony: God has given us eternal life, and this life is in his Son.

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.

because all that is in the world (the desire of the flesh and the desire of the eyes and the arrogance produced by material possessions) is not from the Father, but is from the world.

Now this is his commandment: that we believe in the name of his Son Jesus Christ and love one another, just as he gave us the commandment.

but every spirit that does not confess Jesus is not from God, and this is the spirit of the antichrist, which you have heard is coming, and now is already in the world.

By this love is perfected with us, so that we may have confidence in the day of judgment, because just as Jesus is, so also are we in this world.

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.

(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.)
