I know picking one out of this list will be a hard. After making the list, I realized that it would be a hard choice for me. I narrowed the list of choices down to 3, Thomas Watson, John Bunyan and Richard Baxter.
I picked John Bunyan. His theology was good, but undervalued I believe. Also John Owen said, "He would give up all his learning to preach with the power Bunyan had."
