On Gen 12:10-20
The purpose of such passages becomes clearer when we begin to recognize the typological character of biblical narrative. The story of Abram is given to us as a deep source for our identity as his children and as an anticipation of our destiny as the people of God. As we read the story of Abram’s exodus from Egypt, we are supposed to recognize that this is a ‘Russian doll’ that looks forward to and fits inside the great Exodus accomplished by Christ, in whom we have been caught up. Abram’s story is thus a story in which we need to be able to see both Christ and ourselves, the children of Abraham in the promised Seed.
