"Knocking on Heaven's Door?"

Today I preached for the first time in the "Big Church" at Church of the Incarnation, i.e., in the three traditional services in the main church.  Despite fighting a cold (my voice went after I preached the final time), by the grace of God it went well. (And since the Suffragan Bishop, who was there for the 11:15 version, didn't drag me out of the pulpit, I'm assuming that it also passed theological muster.)  My text was Luke 11:1-13; you can listen to a recording here.  Let me know what you think.
