The idea of getting small bite sized pieces of hope is an interesting thought.  It makes more sense of those Psalms that seem to have so much contrasts in them.  It explains Psalm 22 the best.  When we can take our eyes off of our problems and circumstances even for a moment, and look to God, we can experience a small window of hope, however brief, in which we can rest in God’s strength and power.  And those times can mean the difference between making it through and giving up.  So do not discount the precious gift of even bite-sized hope.  It might not get us all the way to through, it will make those times a bit better.
