I Love this from John Piper:
One of the reasons God rarely gives micro reasons for his painful providences, but regularly gives magnificent macro reasons, is that there are too many micro reasons for us to manage, namely, millions and millions and millions and millions and millions.
God says things like:
- These bad things happened to you because I intend to work it together for your good (Romans 8).
- These happened to that you would rely more on God who raises the dead (2 Corinthians 1).
- This happened so that the gold and silver of your faith would be refined (1 Peter 1).
- This thorn is so that the power of Christ would be magnified in your weakness (2 Corinthians 12).
But we can always object that there are other easier ways for God to accomplish those things. We want to know more specifics: Why now? Why this much? Why this often? Why this way? Why these people?
The problem is, we would have to be God to grasp all that God is doing in our problems. In fact, pushing too hard for more detailed explanations from God is a kind of demand that we be God.
Think of this, you are a blacksmith making horseshoes. You are hammering on a white hot shoe and it ricochets off and hits you in the leg and burns you. In your haste to tend to your leg you let the shoe alone unfinished. You wonder why God let this happen. You were singing a hymn and doing his will.
Your helper, not knowing the horseshoe was unfinished gathered it up and put it with the others.
Later there was an invasion of your country by a hostile army with a powerful cavalry. They came through your town and demanded that you supply them with food and with shoes for their horses. You comply.
Their commander has his horse shoed by his own smith using the stolen horseshoes, and the unfinished shoe with the thin weak spot is put on the commander’s horse.
In the decisive battle against the loyal troops defending your homeland the enemy commander is leading the final charge. The weak shoe snaps and catches on a root and causes his horse to fall. He crashes to the ground and his own soldiers, galloping at full speed, trample him to death.
This causes such a confusion that the defenders are able to rout the enemy and the country is saved.
Now you might say, well, it would sure help me trust God if he informed me of these events so that I would know why the horseshoe ricocheted and burned my leg. Well maybe it would help you. Maybe not.
God cannot make plain all he is doing, because there are millions and millions and millions and millions of effects of every event in your life, the good and the bad. God guides them all. They all have micro purposes and macro purposes. He cannot tell you all of them because your brain can’t hold all of them.
Trust does not demand more than God has told us. And he has given us immeasurably precious promises that he is in control of all things and only does good to his children. And he has given us a very thick book where we can read story after story after story about how he rules for the good of his people.
Let’s trust him and not ask for what our brains cannot contain.
Already Not Yet 
Looking for a plausible reason for pain has been an eternal quest for mankind. C.S.Lewis wrote about this subject.
Unfortunately, it finally comes down to our own explanation, such as those in this article. We have to, it seems, accept pain of all kinds as a mysterious game being played by a loving creator.
I find this unacceptable. Given the extent of suffering in the world since time began, we will continue to hurt ourselves and each other until consciousness in us rises to a very high, the highest ,level, and we see in shame just how pitiful are our reasons for this behaviour. It still doesn’t explain adequately why innocent children suffer and die. What sin did they commit for a god to let them suffer?
Even Jesus was crusified and died innocent for he had commited NO SIN but due to Man kind he was sacrifised.
God will use all ways for us to remember him, the powerful God.
this is an amazing answer. and makes me not freak out so much.
