Abraham is a foundational figure in the history of the church. But he is at the same time profoundly human and raw and real. Isolated in an unbelieving world, his story shows what it means for the Lord to take hold of a sinner, privilege him with promises, use him in his service and sustain him to the end. Given the current cultural dislocation of Christianity, the central thread of Abraham’s life is increasingly relevant. Ultimately, it speaks of a believer looking to a city with eternal foundations, and that story speaks powerfully to us as strangers and aliens in our world.
