How Do You Face Good and Bad Time

How Do You Face Good and Bad Time

Question
How do we explain God to someone who believes that while God exists, they cannot accept or understand how a merciful, comapssionate God would allow so much human suffering to take place. The analogy they give is that if we are God's children, why does God not protect us -- just as a parent would gaurd over their children?
Answer
Praise be to Allaah.
