Questioning is the way of humanity. We will always ask, debate, challenge, and search. However, there is an immense difference between a worldview that is not able to answer every question to complete satisfaction and one whose answers are consistently contradictory. There is an even greater difference between answers that contain paradoxes and those that are systemically irreconcilable.
The Christian faith stands out as unique in this test, both as a system of thought and in the answers it provides. Christianity does not promise that you will have every question fully answered to your satisfaction before you die, but the answers it gives are consistently consistent. There may be paradoxes within Christian teaching and belief, but they are not irreconcilable.
I often put it this way: God has put enough into this world to make faith in Him a most reasonable thing. But He has left enough out to make it impossible to live by sheer reason alone. Faith and reason must always work together in that plausible blend. —Ravi Zacharias (from, Faith and Reason Must Work Together)
