When your expectations are disappointed and life doesnt turn out like you thought it would, you can become disappointed and disillusioned. As aircraft pilots depend upon their navigational control systems to guide them through turbulence when things arent visibly clear, so it is with life in general. When life becomes uncertain due to the loss of a loved one, or any loss for that matter, we need a navigational system to guide us. Faith serves as a dependable system to get us through those times when we dont understand which way to go.
