In the history of mankind, there has been some notable achievements.  The pyramids, hanging gardens, the coliseum.  In more recent times we have harnessed nuclear power, mastered flight, and video chatting across oceans.

But one invention stands above them all: Caller ID.

Now maybe that's a slight exaggeration, but if you've answered the phone and immediately regretted it, you know the power of caller id.  Or more than that, seeing the joy at who is calling you.

In our study of Abraham we've seen him answer the call of God many times.  Joyfully, cheerfully, even slowly.  But for Abraham to know God is calling him is a great joy.  When God calls in Genesis 22, I'm sure he eagerly answers, but this time the call is different.  God asks him to sacrifice his son.


Abraham obeyed, traveling the 3 days with his son to the place of his sacrifice.  Abraham trusted God with simple faith, because he had not seen God let him down.  Even when there was no evidence.  God sent a substitute for Isaac, just as he did for us.  This chapter is a picture of how we must trust God, even when the picture is unclear.  By giving us His Son, God has shown himself faithful to us, and we must never forget it.
