5 9If we receive human testimony, the testimony of God is greater; for this is the testimony of God that he has testified to his Son. 10Those who believe in the Son of God have the testimony in their hearts. Those who do not believe in God have made him a liar by not believing in the testimony that God has given concerning his Son. 11And this is the testimony: God gave us eternal life, and this life is in his Son. 12Whoever has the Son has life; whoever does not have the Son of God does not have life.
