 That's it, just believe. It's not a work at all as we understand work, but it's faith in Jesus Christ who has already done the work for us. One of my favorite preachers of history is a man by the name of George Whitefield. He was quite an evangelist. And you know, when you study these guys and realize they often preach to 20,000 people without any microphones or reinforcement systems, you wonder what kind of lungs these dudes had.
