The laws of nature are very difficult to understand. How did the universe start? Why is the universe endlessly expanding? If the universe is endless expanding, and all matter will eventually be equally spaced at a temperature infinitesimally close to absolute zero, is there any point in doing the laundry? These, and many other questions to do with natural sciences, can be troubling to the point of dysfunction. However, you need and want a cup of tea, and, to make the cup of tea, you'll need to boil the kettle. Separate questions about natural sciences in general from the practical matter of boiling the kettle and trust that the physics behind boiling the kettle will work. Switch the kettle on.
Likewise, separate theological questions about how God 'lets' bad things happen or even causes them from the basic spiritual physics of asking God for direction and strength. If spirituality and theological investigation are too closely linked, every twist and turn of theological thinking will interfere directly in the supply of direction and strength necessary for daily functioning. Focus on the spirituality of trusting and following God's guidance and park theology for when everything is going well. Don't use theology, or, heaven forbid, philosophy, to solve the mood of the moment. It likely won't.
