Hurricanes, health problems, grief. Why does God allow suffering?

Life feels impossible, practically undoable, for so many. From hurricanes and extreme loss to failing relationships and financial stress. All around us, we see so much suffering. And we have so many questions about why life hurts. We want answers to why it happens, and we want relief from how we feel. 

Why does God allow sin and suffering to pass through His hands into our lives? Why does He permit that which He hates to come to fruition?  We know suffering should not surprise us, but somehow it still does.
