Jesus of Nazareth was a Jewish man who lived about 2000 years ago on earth. Why have billions of people put their faith in Him? John says it’s because of God testimony. Testimony is the way we know most things, the same way you know Australia exists—you have it on good authority. We don’t find the truth about Jesus while looking to ourselves and thinking our best thoughts. God bears witness that Jesus is His Son and the Christ. We hear it, believe it, and add our testimony that eternal life is in Christ.
