I appears that this topic is mostly quieted down and that saddens me as it is a very justified, very real and mostly very needed topic in everyone's life. The reasons are numerous but in keeping it short I'll not quote scripture and/or step on a pulpit. Instead I'll simply state that it is of my opinion that too often we (non believers and believers alike) confuse this very topic.
Read up and the one word most often used is "belief" when in fact it is not belief at all that is in question. The original question should be related to "faith" as faith and belief are two different things. Posters above mention the soul journey and the importance it is to take that journey to reinforce that which you believe for you see, in order to belief one must have faith and faith comes through the journey of searching.
Again, if one has all the belief in the world but has no faith in that belief does one actually have anything at all? Paul teaches us in first Corinthians that we are all one body of Christ. That within that body there are many differences and that no single part of that body is greater then the other and frankly that each part needs the other. So... in knowing this we also know that the one body doesn't exist without faith. Questioning your religion is not only acceptable but necessary as it is in this questioning that you will find "your" faith and in finding that (your faith) you will also find that you strengthen belief but not just your belief but also the body of your belief.
As for answering the comment above
I find myself wondering if you asked yourself the simplest of questions. Too often we make faith to hard by overlooking the simplest of things. The one question rarely asked is this. Is there another proclaimed king that loved his people so that he gave himself as a sacrifice? Ponder that, reflect on his teachings, (love your enemy, turn the other cheek, feed the poor, cloth the naked, heal the sick, walk peacefully with love) ... Yes, the science of today and the non-believers will point to things that aren't explained by faith but they do so while staying blinded to the evidence that only faith provides. You ask what those are? Everyday unexplained miraculous healing, unexplained examples of someone saved by a mystery miracle person, gold dust falling from the ceiling and covering the floor or those who have died and then returned saying they were told by Christ that it wasn't yet their time.
So.. yes, questioning your religion is something we all need to do so that in our answers we build and strengthen our faith.
If a King born has power, has fear, has greed, has desire and has people willing to die to defend him/her why then is it that we have but one King whom said we should love our enemy and turn the other cheek? His faith in that belief was so strong that he went to the cruelest of deaths without asking his followers to risk their lives.
