Today's Communion antiphon, 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. This post segues nicely from the previous one. The key phrase in the above verse is "open the door to me." If you are attentive, you'd hear the Lord speaking constantly to us. If we would only open the door after hearing each knock, our life would change completely. Again, humility and submission are required for it to happen.
