...God is working on your ability to trust Him.
This is the substance of relationship. He's the one from whom relationship, intimacy originates. He knows the ingredients.
Maybe your life is peachy. Maybe it is terrible. Whatever the case, run it through this filter: God is passionate about teaching humans to trust Him. That may help to catch erroneous thinking ("God is a bad dad," "God takes too long to come through," etc). The process of creating trust is often costly, often difficult. It's worth it to God (it's even worth dealing with frustrated humans).
