Faith in God is not merely a matter of personal opinion. According to the Bible, faith (belief) is based upon such evidence as testimony (Romans 10:17) and the nature of the universe (Psalm 19:1; Romans 1:20). Faith, then, is supported by facts and information rather than merely being an assumption or “leap into the unknown”. Christianity is not based upon “blind faith”.
In regard to the evidence of testimony, consider the Biblical book of “John” (the fourth book of the New Testament). This book provides a record of Jesus’ earthly ministry. But it is much more. John describes his purpose as follows: “Now Jesus did many other signs [miracles] in the presence of the disciples, which are not written in this book; but these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name” (John 20:30,31). John thus declared that he had presented sufficient evidence (testimony) to indicate who Jesus was.
So it is in regard to the Bible and God. The Bible contains considerable historical, geographical and biographical information which can all be put to the test. When such material is studied, it is found to be reliable. Biblical reliability continues into the matter of miracles (which themselves act as evidence – “signs”). Among the most significant of Biblical miracles (apart from the original creation) was the resurrection of Jesus from the tomb. Extensive evidence supports the historical reliability of that event. Thus, the Bible is shown to be in many ways a reliable source of testimony. And that reliable source of testimony strongly affirms the existence of God. (It should not be overlooked that the life, teaching, miracles and resurrection of Jesus are an integral part of that testimony.)
In addition to that are the existence, complexity and harmony of the universe. Yes, there are various theories regarding the origin of our universe. Some are mere speculation and some have been scientifically disproven. Some merely push the question of origins back to that of a supposedly earlier or “super” (mother) universe. The study of such matters leads us into the field of “cosmology” – a field so full of theory as to have been described as “a mountain of speculation suspended upon a thread of facts”. This is not to deny the validity of science and of scientific research into the nature of the cosmos but it does caution us against assuming that science has ruled out the existence of God.
A current theory is that the universe could indeed arise out of nothing without any necessary cause. This is proposed to have occurred as a result of fluctuations in a quantum field. But are “fluctuations in a quantum field” really the same as something (an enormous universe) arising out of “nothing”? And even if such a possibility is considered, what established the laws governing “fluctuations in quantum fields”? Where did such laws and events arise from?
But far beyond such speculative matters lies the fact of the amazing complexity and integration of our universe, from the atomic and microscopic levels through to the macroscopic. Is it all merely the accidental result of countless millions of lesser accidents? Or does widespread evidence of design in the universe point to the existence of a Designer?
Truly, this is a vast subject to try to consider adequately in just one page. But there is evidence of design in the universe. There is evidence concerning the deity of Jesus Christ and the reliability of His teachings. There is evidence regarding the credibility of the Bible. All of this together provides strong evidence that there is indeed a God. If you would like to consider this question further, let us know.
