What would likely happen if pastors emphasized repentance in their sermons?

Kevin Swanson explains in this video that if pastors emphasized repentance in their lives, in the ministry of the church, and in their preaching, we would see a reformation of life. We would see a reformation of all the areas of life that have been contaminated by the world. 

We would see people seeking to change various areas of their life. They would be crying out for repentance for themselves and the culture. They would seek a cleansing of all areas of their lives and desire to see all of life reformed. 

Romans 12:2 (NKJV) - "And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God."

If repentance was a true emphasis in the lives of the elders and the pastors, in the ministry of the church and the preaching, I think you would see a radical transformation of all of life. I think you would begin to see a reformation of all those areas of life that have been contaminated by the world. We would see people seeking areas in which they would want to change their perspectives. The way they want to change, the way they view education, the way they view art, culture, movies. They wouldn't walk into a movie theater and hear God's name taken in vain 20 or 30 times and walk out and high-fiving their friends say, that was a great movie.

They'd be overcome with shame that they were in that movie theater and enjoying the blasphemy and the The godlessness and the absence of the fear of God in this cultural presentation. They'd be overwhelmed with shame and disgust And they would be crying out for repentance, not just for themselves, but also for their cultural institutions. They would want to see all of life reformed, their politics, their art, their culture, their education, their media. They would seek a cleansing of all of the various aspects of their lives.
