I don't know steve quayle but I typically don't completely write someone off or accept everything they say.
Chuck Missler had a very interesting approach and I agreed with much of what he said in direct relation to the saving gospel. (can't remember even one large difference or disagreement off the top of my head not having listened to any of his work in over a year)
A lot of the other stuff which relates science or theories or history I may differ from more.
I expect to see Chuck in heaven because I believe his faith was in Christ.
