'Testimony' in the Bible

If we accept human testimony, God's testimony is greater, because it is the testimony of God and because he has testified about his Son.

The person who believes in the Son of God believes this testimony personally. The person who does not believe God has made him a liar by not believing the testimony that he has given about his Son.

This is the testimony: God has given us eternal life, and this life is found in his Son.
