R. G Lee was said to have preached Payay Someday over 1200 times and people would drive for many miles to hear it again when he was in their state.
If it's your sermon that God gave you and it continues to move people then I see nothing wrong with preaching it as you travel.
Do you really believe R. G. Lee didn't get that sermon from someone else?
I remember Jack Hyles saying he never preached a sermon on the road that he had not preached to his own people first.
Hyles was a crock and shyster. Why would you enjoy such people?
I also remember him saying his secretary recorded where he preached each of his sermons while preaching out so he would not preach the same sermon within 100 of a meeting he had preached it before, He did niot want people you came to hear preaching to hear the same sermon over and over.
The show must go on.... I suppose his secretary replaced the "Holy Spirit" in his efforts.
If a sermon helped people in one church or one area why would a preacher not preach it again in another state or area?
It helped Hyles. Which is the point.
