Q. How can one be certain that Jesus Christ is God? Is there scientific evidence?
A. Excellent question! Many reilgions will ascribe to Jesus great respect, but only Christianity embraces him as God. For the sake of argument, I will assume you agree that the Bible clearly teaches that Jesus is God. If I am wrong in this assumption, then I would direct you to consider the gospel of John, which was written with the intent of demonstrating that Jesus is God. The theme verse for this book is found in chapter 20, verse 31...."But these [things] are written that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.".The root of your question seems to be, "Is the Bible a reliable record upon which I can place my confidence, or is there some other source that would verify that Jesus is who he claimed to be?". Here are some facts about the Bible: It is unique in it's continuity.It was written over a 1600 year span, involving over 60 generations, written by more than over 40 authors from many walks of life including fisherman, a doctor, a shepherd, a military leader, and a political leader, among others. It was written on 3 continents, written during many different times and moods (war, peace, joy, sorrow, etc.), and written in 3 different languages. With all this diversity, the plainly remarkable thing about this book is that it has a unifying theme throughout it's pages....that of God rescuing a fallen mankind, and desiring close relationship with man. It is unique in it's circulation. "The Bible has been read by more people and published in more languages than any other book." (Josh McDowell, Evidence that Demands a Verdict, 1972, p.21) It is unique in its survival. "The Bible, compared with other ancient writings, has more manuscript evidence than any ten pieces of classical literature combined...". (ibid.,21) As far as your question about science....The repeated experimentation/observation aspect of science is not helpful to us in this situation, and archeology is the main "science" that would help us most in anwering your question. Archeology finds have, to my knowlegde, never disproven the Bible. Rather, sceptics have been disproven time and time again when new discoveries bolster the testimony of the Bible. A lifetime of study would prove insufficient to plumb the depths of your question, but I have offered a tiny thought or 2 about the Bible. In summary, the Bible is unquestionably unique, it is historically and archeologically reliable, and it calls you and I to submit to it's claim as the Word of God. As to your specific question about the Bible's testimony about Jesus, science has not disproven the claims of Christ, and archeology supports the Bible's testimony. "How can you be certain Jesus is God?". There will always be an element of faith when it comes to these things. However, biblical faith is not a blind leap in the dark, but rather it is a call to faith based on ample evidence provided by God in 1) Creation (nature) and 2) The Bible. The Bible does not stop at answering the question "Who is Jesus?". It asks the follow up question, "Will you trust in Him for eternal life?". Faith in him alone is the only remedy the Bible offers for your sinful offensiveness to a holy God. Jon
