A Christian doesn't avoid the questions; a Christian embraces them. Questions are not scary. What is scary is when people don't have any. What is tragic is a faith that has no room for them.
Central to the Christian experience is the art of questioning God. Not belligerent, arrogant questions that have no respect for our maker, but naked, honest, vulnerable, raw questions, arising out of the awe that comes from engaging the living God.
This type of questioning frees us. Frees us from having to have it all figured out. Frees us from having answers to everything. Frees us from always having to be right. It allows us to have moments when we come to the end of our ability to comprehend. Moments when silence is enough.
