Genesis 18-30

I recently heard N.T. Wright say that reading the Bible should be like going to the symphony.  You should walk away from the experience moved by the grand composition.  You may not recall the specific notes of the 2nd movement, but you should be affected by the entirety of the experience.  His point was that often we read the Bible in such small bites that we miss the greater narrative taking place (he clarifies that detailed study of Scripture is also worthwhile).
The thread that seems to run through Genesis 18-30 is the promise of God.  Over and over again God repeats his promise to Abraham, Isaac, and Jacob.  Hundreds of years pass in these chapters, while the heirs of the promise vacillate from faithfulness to deceitfulness; but God's faithfulness to the promise is the consistent over-arching element throughout.  I imagine that as God composed his symphony, he anticipated that the listeners would forget some of the names and places; but I imagine that His hope would be that the listeners be moved by His faithfulness to the promise.
May my life today be affected by these ancient stories of God's faithfulness to the promise.
