People who suffer misfortune often ask why bad things should happen to them or even question God's existence. This is understandable. Well, our world is an imperfect, sinful place; therefore, bad things must happen. It's what happens to you at the end that will justify everything. Putting it simply, a good person will enter heaven and a bad person won't. At that time you will see the overall picture and understand everything, for God is perfectly just. There is no other good explanation.
