People rightly refuse to believe without evidence. Since God created humans as rational beings, he expects them to live rationally, to look before they leap. This does not mean there is no room for faith. But God wants us to take a step of faith in the light of the evidence, rather than to leap in the dark. Evidence of truth should precede faith. No rational person steps into an elevator without some reason to believe it will hold him up. No reasonable person gets on an airplane that is missing part of one wing and smells of smoke in the cabin. People deal in two dimensions of belief: belief that and belief in. Belief that gives the evidence and rational basis for confidence needed to establish belief in. Once belief that is established, one can place faith in it. Thus, the rational person wants evidence that God exists before he places his faith in God. Rational unbelievers want evidence that Jesus is the Son of God before they place their trust in him.
