What do you say to people who come up to compliment your sermon? On the one hand positive feedback is good and necessary, when the sermon merits it. On the other hand, we seek to proclaim the truth of God by the power of God, not by our own wit and wisdom. What do you say to the person who tells you that you’ve done a good job? “Thank you” seems to take credit. “Only by God’s grace” seems a little pompous. I usually go with “thank you” or “keep praying for good sermons” and leave it at that. Perhaps I should try “Thank [or Praise] God if this word has been used to bless you.”
