No, we need Biblical Christ-centered preaching and Holy Spirit regeneration.
Now you're preaching! Preach it!
Old fashioned preaching usually IS Christ centered, compared to what some churches do today. Yes, we do need Holy Spirit regeneration, which I do see in some of our churches that are spirit-filled churches, and not in a lot of mainstream churches. I believe that’s it’s coming though, as God moves across our nation in revival.
