Everyone likes Lester Roloff, but he was a bit of an iconoclast. Have you heard his famous sermon “The Mule Walked on”? There are very few IFB preachers who’d agree with that sermon, even when he preached it.

I’ve heard a lot of his sermons, in person, having been a Bethesda girl in the 70s. I don’t agree with every jot and tittle of what he said, mainly in regards to food (though his regimen gave me some good habits which have stayed with me). But I agree with him on every salvational issue, and the fruit of salvation.
