It reinforces two things for me. First that although we are charged as teachers and leaders to handle the Word accurately, it is not the accuracy of how we handle the Word that gives it power. That power lies in the fact that God has ordained it to do what He wants it to do (See yesterday’s post). That does not let us off the hook for prep, it just reminds us where the credit goes.
Second, that unless the Holy Spirit is moving to teach a person, they are not going to learn. If the Spirit is moving they are. So the Spirit can take efforts that are not all that great and significantly bless a believer through what is shared. He has done that with presentations I have made.
Third (this one is free) if I am not getting anything out of the event, I probably need to check and see if I am shutting the Spirit out.
