Missionary Evangelist Robert Breaker in his own local church assembly meeting speaks about those who throughout history have PERVERTED the gospel, and it how it appears it's often because they themselves are PERVERTS in their lifestyles, living in sin.

He also talks about having to leave his old church because he saw perversion and a changing of the how they preached the gospel. For more on that, click here:
