Well .. I would not go to a church where the sermons were canned. If my Pastor was not praying and getting his stuff from GOD - then I don't want to hear it.
I personally knew my Pastor didn't do that .. and sometimes he would get all prepared with a sermon and the Holy Ghost would begin moving - he could close his notes and just preach what the Holy Ghost gave him. Those were some of the most scripture filled - Holy Ghost working services if I have ever been in.
AMEN! AMEN!
