Questions of Faith

I have recently been questioning my faith in a big way. How is it possible that if there is a higher power managing the human race, that children and infants can get horrible diseases and die??? I have recently heard of a family that I know that has three children, 6, 4 and 6 months old. The 6 month old went into the hospital a few weeks ago and his whold body is riddled in cancerous tumors. How is this just??? What part of unfair does this not describe??? I just don't know. The baby is now in paliative care and will die any day now. The parents and family are in shock. How does this happen? Why does it happen to the most innocent? I just don't know.
