Secondly, politely thanks them for their kindness, and gently direct them towards the One they should really be thanking, for it is certain that any benefit they recieved from your service was due to the Holy Spirit working in them, not your own cleverness.

Guide them back to the topic at hand, the actual substance of your talk, rather than the critical assessment of the talk or the talker.

How do servants who give talks/sunday school lessons deal with ‘critical acclaim’ after a sermon, lets say someone comes to you and “wow” your talk was amazing, I know we should give god the glory but what should we say.

I think it is a worthy point, that often people (including myself) are too involved in criticism that they miss the point entirely- and walk away with an analysis than a message. It is an opportunity lost.
