For there are three that testify:

These things I have written to you who believe in the name of the Son of God, so that you may know that you have eternal life.

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

This is the confidence which we have before Him, that, if we ask anything according to His will, He hears us.

Whoever believes that Jesus is the Christ is born of God, and whoever loves the Father loves the child born of Him.

the Spirit and the water and the blood; and the three are in agreement.

For whatever is born of God overcomes the world; and this is the victory that has overcome the world—our faith.

For this is the love of God, that we keep His commandments; and His commandments are not burdensome.

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

And we know that the Son of God has come, and has given us understanding so that we may know Him who is true; and we are in Him who is true, in His Son Jesus Christ. This is the true God and eternal life.

He who has the Son has the life; he who does not have the Son of God does not have the life.

If anyone sees his brother committing a sin not leading to death, he shall ask and God will for him give life to those who commit sin not leading to death. There is a sin leading to death; I do not say that he should make request for this.

We know that no one who is born of God sins; but He who was born of God keeps him, and the evil one does not touch him.

And if we know that He hears us in whatever we ask, we know that we have the requests which we have asked from Him.

All unrighteousness is sin, and there is a sin not leading to death.

Who is the one who overcomes the world, but he who believes that Jesus is the Son of God?

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 given concerning His Son.

Little children, guard yourselves from idols.

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.

If we receive the testimony of men, the testimony of God is greater; for the testimony of God is this, that He has testified concerning His Son.

By this we know that we love the children of God, when we love God and observe His commandments.
