Benedict XVI is giving a series of teachings on the Creed.  Here is a teaser from his first one:

Faith leads Abraham to tread a paradoxical path. He will be blessed, but without the visible signs of blessing: he receives the promise to become a great nation, but with a life marked by the barrenness of his wife Sarah; he is brought to a new homeland but he will have to live there as a foreigner, and the only possession of the land that will be granted him will be that of a plot to bury Sarah (cf. Gen23:1-20). Abraham was blessed because, in faith, he knows how to discern the divine blessing by going beyond appearances, trusting in God’s presence even when his ways seem mysterious to him.

A lot to think about there.  If you’d like to read his whole address, you can go here.
