“The evidence required to prove something exists must correspond to its nature. For example, the evidence offered as proof for the existence of gravity is not the same kind that is used to prove a mathematical theory. In the same way, proof for God’s existence corresponds to what the Bible reveals about the nature of His Being.
Since the Bible reveals that God is not a part of the physical universe then He cannot be seen with the physical eye nor can his existence be verified through scientific investigation. Those holding a materialistic view of the universe will object to this, of course, because they presuppose that reality is composed essentially of matter and energy. Thus materialism in and of itself amounts to an a priori53 rejection of the God of the Bible.
Since non-Christian worldviews contain presuppositions that differ from those in the Christian worldview, the disagreements about whether or not Christianity is true involve much more than dispute over certain facts. Questions involving God’s existence as well as what kind of God He is will always involve a worldview conflict between the Christian and non-Christian. Can such a dispute be resolved to any satisfactory conclusion? The answer is yes.”
