One of today's Communion antiphons, Revelation 3.20: Behold, I stand at the door and knock. If anyone hears my voice and opens the door to me, I will enter his house and dine with him, and he with me. I believe that most of us, in USA here anyway, have heard the Lord's voice at one time or another, albeit sometimes only faintly, but never bothered to open the door for even a peek. And this is tragic. In today's Gospel reading from Matthew 13, Jesus explained to his disciples why he spoke in parables to the people. He said it's because they look but do not see and hear but do not listen or understand, fulfilling Isaiah's prophecy. That Isaiah described the heart of the people as gross is still accurate today.
