Mr. Bolton's book was the means of the conversion of Gifford, who, in turn, led Bunyan into the light, and, consequently, to the writing of that wonderful book, "The Pilgrim's Progress," in which Gifford is supposed to be the Evangelist, who points out to Pilgrim the wicket gate. Who shall measure the power of a good book!
For months, even years, Bunyan passed through the struggles which Pilgrim found in his difficult journey. He has glowingly depicted these in his "Grace Abounding to the Chief of Sinners."
Sometimes he was in the depths of despair, because he felt that his sins had been too great to be forgiven. Then he feared that he was not one of the elect, or that he had committed the unpardonable sin against the Holy Ghost. Then doubts about the Bible and God took possession of him, till, under the mental strain, his health became affected, and consumption seemed imminent.
Sometimes a promise from the Bible would bring him the greatest joy. "I was now so taken with the love and mercy of God," he writes, "that I thought I could have spoken of it even to the very crows that sat upon the ploughed lands before me, had they been capable to have understood me."
In these days of alternate grief and joy, Bunyan came upon an old copy of Luther's "Commentary on the Galatians;" "so old, that it was ready to fall piece from piece if I did but turn it over.... I found my conditions as largely and profoundly handled, in his experience, as if his book had been written out of my heart. I do prefer this book of Martin Luther (excepting the Bible) before all the books that ever I have seen, as most fit for a wounded conscience."
This book was also most effective in the experience of John Wesley. "I went," Wesley wrote, "very unwillingly, to a society in Aldersgate Street, where one was reading Luther's Preface to the Epistle to the Galatians. About a quarter before nine, while he was describing the change which God works in the heart through faith in Christ, I felt my heart strangely warmed. I felt I did trust in Christ, Christ alone, for salvation, and an assurance was given me that he had taken away my sins."
Finally, "the peace of God which passeth understanding" came into Bunyan's heart. As he was walking in the field, he seemed to hear the sentence, "Thy righteousness is in heaven;" "and methought I saw," he says, "with the eyes of my soul, Jesus Christ at God's right hand, there I say, as my righteousness, so that wherever I was, or whatever I was doing, God could not say of me, he wants my righteousness, for that was just before him. Now did my chains fall off my legs indeed. Now went I home rejoicing for the grace and love of God."
During these years of anxiety, Bunyan worked hard with his hands, feeling, as did his honest father, that it was one of the first of duties to be "very careful to maintain his family." He had been moderately successful at his trade, as a contemporary biographer writes, that "God had increased his stores so that he lived in great credit among his neighbors."
In the year 1653, when he was twenty-five,—the year in which Oliver Cromwell was made Lord Protector of England,—he became a member of Mr. Gifford's church. He probably removed to Bedford from Elstow, two years later, and was made a deacon in the church.
