Christianity Is Rationally Uncertain
Yes, it must be if it is to do anything for us as individuals. Faith therefore, requires a leap. It is not a matter of galvanizing the will to believe something there is no evidence for, but a leap of commitment.
Kierkegaard says “The leap is the category of decision”– the decision to commit one’s being totally to a God whose existence is rationally uncertain and whose redemption is utterly an offense. All proofs for the existence of God and the deity of Christ fail. What if Christianity is not a doctrine to be taught, but a life to be lived?
In which case proofs would not only be unconvincing, but irrelevant.
