\v 9 If we receive the witness of men, the witness of God is greater. For the testimony of God is this—that he has borne witness concerning his Son.
\v 10 He who believes in the Son of God has the testimony in himself. Anyone who does not believe God has made him a liar, because he has not believed the witness that God has given concerning his Son.
\v 16 If anyone sees his brother commit a sin that does not result in death, he must pray and God will give him life. I refer to those whose sin does not lead to death. There is a sin with leads to death—I am not saying that he should pray about that.
\v 17 All unrighteousness is sin—but there is a sin that does not lead to death.
\v 20 But we know that the Son of God has come and has given us understanding, that we know him who is true, and that we are in him who is true—even in his Son Jesus Christ. He is the true God and eternal life.
