What if?

What if something very foundational to your very essence, something that, in part, defines who you are, something that you have held and believed for as long as you can remember, is wrong? 
The first thing to acknowledge is that you will not let go of this something very easily.  Foundational presuppositions are, usually, things we don't even think about, but simply embrace. They are things we believe without questioning.  We need to recognize that if one of these presuppositions are pointed out, identified and brought to light, so as to be questioned, we should be thankful.  The thing about the historic Christian faith is its unfailing solidity.  Any question, all questions for that matter, can be answered by the Church.  This is not to say that the logician or rhetorician will necessarily be satisfied with any particular answer given, but this has more to do with THEIR presuppositions rather than the validity of the answer.
So as followers of Christ, we have nothing to fear.  Ask any question and seek out any valuable knowledge.  For when you do, the right answer will lead you to Christ. One can almost guaranteed that everyone has some area or some belief that is erroneous.  Be thankful when you find it and embrace the discomfort of challenging it.  This is called growth.  Life is either growth or regression, we never stand still.
