It is true that God is good and that in the world under His control bad things happen – at least bad things happen from the human perspective. When I discipline my child, it might seem like a bad thing from his vantage point, but it is a good thing from mine. When a nation wins a just war, it might seem bad from the enemy’s side, but it is good for the world. So at least part of the problem is perspective. Are we saying something is bad from God's perspective or man’s?
