After being raised in the United Methodist Church, in my mid 20's I came across the voice of
Roy Masters on the radio one night and became influenced by his teachings to the point that I soon began denying the deity of Christ. He made a lot more sense to me at the time than any Christian minister I had ever heard since all I had ever heard was ignorant evangelicals, liberals and Romanists. I never really got into practicing the meditation exercise he teaches though.
After a couple of years of listening, I began to notice contradictions in Masters' teaching and was converted while reading the Dave Hunt books "A Woman Rides the Beast" and particularly, "Occult Invasion".
Later I began listening to Family Radio, but I was never tempted by Camping's rantings on the end of the church age. I listened to Family Radio to hear Lloyd-Jones, Barnhouse, Lutzer, John R. DeWitt, Boice, etc. But of course all of those programs are now gone.
I've also come across Stair on the radio. I think his program literally runs 24-7 on AM, SW and the internet.
