Genesis 22-26: God will provide

The story of Abraham's willingness to sacrifice Isaac is a familiar one.  Trusting God, that is something that Abraham had learned to do through trial and error perhaps, but by the time Isaac was a young boy, he had walked with God long enough that he knew the God he trusted.  So when Isaac ask him where the sacrificial lamb was, the first thing that came out of his mouth was that God would provide the lamb for the burnt offering.  A few years later, when it became time to get a wife for his son Isaac, Abraham still knew that God would provide.  And he provided Rebekah from Abraham's own family line.  With the exception of Isaac, Abraham's faith in God's ability to provide contrasts sharply with that of his descendants and relatives.  Isaac must have learned the lesson well, because later when the second famine comes to the land, he refuses to go down to Egypt because he knew that the Lord would provide.  Abraham leaned his lesson about what scheming produces, but that lesson failed to be passed down.  Isaac had a taste for the wild and loved his wild son Esau who was more interested in the here and now than in waiting for God's provision.  He sold his birthright for some stew just because he was hungry at that moment. Always the impatient one, Esau finally married two local Hittite women.  Was he so busy out hunting and fishing that he didn't think about a wife until he was forty years old?  By that time, and rather than sending off for a wife like his mother, from his own family lineage, he chose two local women who were a constant source of grief to Isaac and Rebekah.  So much for hasty, untrusting decisions.
