I read the following tonight in Philip Yancey's excellent book Prayer, Does It Make Any Difference?:

Prayer, and only prayer, restore my vision to one that more resembled God's. I awake from blindness to see that wealth lurks as a terrible danger, not a goal worth striving for; that value depends not on race or status but on the image of God every person bears; that no amount of effort to improve physical beauty has much relevance for the world beyond.

Alexander Schmemann, the late priest who led a reform movement in Russian Orthodoxy, tells of a time when he was traveling on the subway in Paris, France, with his fiance. At one stop an old and ugly woman dressed in the uniform of the Salvation Army got on and found a seat nearby. The two lovers whispered to each other in Russian about how repulsive she looked. A few stops later the woman stood to exit. As she passed them she said in perfect Russian, "I wasn't always ugly." That woman was an angel of God, Shmemann used to tell his students. She opened his eyes, searing his vision in a way he would never forget.
