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

I am writing to you, fathers, because you know him who is from the beginning. I am writing to you, young men, because you have overcome the evil one. I write to you, children, because you know the Father.

I write to you, fathers, because you know him who is from the beginning. I write to you, young men, because you are strong, and the word of God abides in you, and you have overcome the evil one.

But you have been anointed by the Holy One, and you all have knowledge.

No one who denies the Son has the Father. Whoever confesses the Son has the Father also.

No one who abides in him keeps on sinning; no one who keeps on sinning has either seen him or known him.

Little children, let no one deceive you. Whoever practices righteousness is righteous, as he is righteous.

No one born of God makes a practice of sinning, for God's seed abides in him; and he cannot keep on sinning, because he has been born of God.

By this it is evident who are the children of God, and who are the children of the devil: whoever does not practice righteousness is not of God, nor is the one who does not love his brother.

Love One Another

For this is the message that you have heard from the beginning, that we should love one another.

We should not be like Cain, who was of the evil one and murdered his brother. And why did he murder him? Because his own deeds were evil and his brother's righteous.

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

God Is Love

Beloved, let us love one another, for love is from God, and whoever loves has been born of God and knows God.

Beloved, if God so loved us, we also ought to love one another.

No one has ever seen God; if we love one another, God abides in us and his love is perfected in us.

Who is it that overcomes the world except the one who believes that Jesus is the Son of God?

Testimony Concerning the Son of God

This is he who came by water and blood—Jesus Christ; 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 anyone sees his brother committing a sin not leading to death, he shall ask, and God will give him life—to those who commit sins that do not lead to death. There is sin that leads to death; I do not say that one should pray for that.

We know that everyone who has been born of God does not keep on sinning, but he who was born of God protects him, and the evil one does not touch him.

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