Sorry for the hiatus; I'm a trifle busy right now and don't have a lot of time for leisurely reading. But, I decided to carve out a few minutes every day for Heschel.
While I might quibble with some of what he says here, I think that on the whole, he is correct. Prayer isn't about us! It's about God. I read somewhere the other day that Mother Theresa was once asked how she prayed. She replied, "I listen." The questioner then asked what God said. She replied, "He listens." After a pause, she continued, "And if you don't understand what that means, I can't explain it." Yep.
