“And we have seen and testify that the Father has sent his Son to be the Savior of the world.”
The New Testament was written by people who walked and talked with Jesus. They saw his miracles, they heard his amazing words. They were eyewitnesses.
Several first- and second-century manuscripts still exist that were passed down from some who actually knew the eyewitnesses. A few were even written during the late lifetime of the last living apostle, John. The Bible has more existing ancient manuscripts (over 5000) than any ancient writing in the world.
Read the New Testament. It was written by inspired men with a passion that would not let them stop talking about this Jesus. He consumed their life when he was on earth, and consumed their spirit after he left.
Through the centuries, men and women have given their lives so that you today may have the writings (New Testament) of those eyewitnesses in our own language and read it for yourself. Many were ridiculed and tortured terribly, and then died a long excruciating death so that the apostles’ testimony could live on.
Do not take for granted your New Testament ~ the words of Jesus’ eyewitnesses. Jesus lived and died for you. Those witnesses, in a sense, also lived and died for you. Read what they testified to. Then, live, and if necessary, die for it.
