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.
Once again, the Christian faith stands out as unique in this test, both as a system of thought and in the answers it gives. 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. To those who feel that Christianity has failed them because of prayers that went unanswered, it is important to realize what I am saying here.
