I think about Job wrestling with an angel. He spent the night doing that, and ended up with a blessing (and a limp!). I think that God respects the fact that we CARE enough to wrestle. So I don't get anxious if I find myself wrestling. In fact, the name Israel MEANS "wrestles with God" (although not sure if that is 'wrestled' or 'wrestles'). A name not to be ashamed of.
Secondly, I think of Mary Magdalene at the tomb of Jesus. All her expectations and hopes died with Jesus. But she loved him still, and when Jesus appeared to her after his resurrection she was blessed for that. When I have felt struggles, I tell myself to wait like Mary at the tomb.
Lastly, exactly as Narkissos said, it takes faith to test faith. Therefore, I feel like I take a great breath and dive in and see in what way God will 'come through', even if it results in a paradigm shift for me, or another perspective to understand. I must bring faith with me into this, an expectation that God won't supply a cut-rate answer for a very important need. I think the journey/waiting experience of seeing how God brings an answer for me is just as--if not more--important than getting an answer.
My trust in God definitely grows thru being stretched in the silences and the wrestlings. These are more fertile than the mountaintop times, I think. (But, like physical exercise, I still try to avoid them!! )
