1 John 5:9-13

If we receive human testimony, the testimony of God is greater; for this is the testimony of God that he has testified to his Son. Those 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. And this is the testimony: God gave 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.
