Do you often "wrestle" with God? Asking him "why do you allow this" or "how could this happen"?
If so, I would encourage you to read the book of Habakkuk. Just 3 short chapters, but I bet as you read it you will find yourselves in Habakkuk's shoes more often than not. It's interesting to see the dialogue of Habbukuk asking "why" and God's response. Reading this helped give me some perspective on the reason behind God's plan, who is in control and what (or Who) is ultimately coming.
