Upon listening to another David Wilkerson sermon audios. I heard this one.When Preachers Do Not Preach Against Sin by David Wilkerson.I think ANYONE giving the gospel message should hear this one. Also bring that in with Ray Comfort's teachings. And you got a great combination."You don't just preach against sin, with your hands flailing and with an angry tone, but with your heart in your messsage; if you want people to hear your message, cry, have your heart and soul in it". David Wilkerson (paraphrased) from this audio.
