For there are three that testify:
the Spirit, the water and the blood; and the three are in agreement.
We accept human testimony, but God’s testimony is greater because it is the testimony of God, which he has given about his Son.
Whoever believes in the Son of God accepts this testimony. Whoever does not believe God has made him out to be a liar, because they have not believed the testimony God has given about his Son.
And this is the testimony: God has given us eternal life, and this life is in his Son.
Whoever has the Son has life; whoever does not have the Son of God does not have life.
I write these things to you who believe in the name of the Son of God so that you may know that you have eternal life.
This is the confidence we have in approaching God: that if we ask anything according to his will, he hears us.
And if we know that he hears us—whatever we ask—we know that we have what we asked of him.
If you see any brother or sister commit a sin that does not lead to death, you should pray and God will give them life. I refer to those whose sin does not lead to death. There is a sin that leads to death. I am not saying that you should pray about that.
All wrongdoing is sin, and there is sin that does not lead to death.
