We all have bad days.  Not counting when someone close to me died, probably the worse bad day that I can remember occurred about ten years ago.  We had a rare blizzard in the Washington/Northern Virginia area that dropped about sixteen inches of snow.  I shoveled out my car only to discover I had a flat tire.    
    There is a tendency when bad days happen to blame God.  Why did God make it happen, or why dis God allow it to happen.  The answer is that it had nothing to do with God.  Bad things happen because of the work or Satan and his demons who want to convince us that God doesn't exist or doesn't care about us.  They also happen because we have drifted away from God.  Our egos cause us to believe that we are very important so God should be doing everything he can to protect us.  That, unfortunately, is simply not the case.  Unless we are a very spiritually advance person, God probably has little interest in us.  He does protect humans overall to some extent, allowing Satan and the demons to only go so far, but even people who have dedicated themselves to God sometimes need to be reminded through adversity that this is not God's world, otherwise, we would have little reason to try to return it to it's spiritual origin.
