How often in life do we react (over-react?) to something when we lose our sense of proportionality. Fear can grip and our minds extrapolate to the "worst case" or "nth degree". Maybe that's part of why I enjoy flying so much -- the perspective from even a few thousand feet above the ground affords just a small reprieve from the sometimes overwhelming nature of everyday life.
Yet most important is to trust God, whose infinite power and love dwarfs all fear and despair.
"For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD. For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts." (Isaiah 55:8-9)
