Young John Bunyan (1628–1688) hardly seemed fit for preaching. He was a coarse person with little education and a mouth full of foul language. He had lost his mother and sister to death and was exposed to the evils of military service before his seventeenth birthday. As a young man, he worked with his hands as a tinker or worker in soft metals. His soul was probably much like his body after carrying his sixty-pound portable anvil: outwardly tough and calloused, though inwardly bruised and burdened. Marriage to a church-going woman brought some moral improvement and produced much self-righteousness, but it was not until Bunyan overheard a few poor women talking about the new birth and the grace of God in Christ for sinners that he realized his greatest need.
The faithful pastor of those women, John Gifford, taught Bunyan about the grace of God. Bunyan read Martin Luther’s Commentary on Galatians and learned how Jesus Christ made satisfaction to divine justice for our sins by His death. Bunyan was transformed, and others soon called upon him to speak in meetings for evangelism and exhortation. Feeling very unworthy, he nevertheless was able to speak from his experience of the truth: “I preached what I felt, what I smartingly did feel, even that under which my poor soul did groan and tremble to astonishment.” He was not a fire-and-brimstone preacher who looked down on unbelievers, but one who lived with a “fire in mine own conscience.”
