John Bunyan was in prison for 12 years. There he wrote one of the best sellers of all time. The Baptist tinker painted Moses and the Law with such striking imagry that you must keep reading. The dialogue is Faithful telling Christian of the assaults he has met on his journey. Faithful describes an old man he met named Adam the First, who tried to persuade him to go to his home and be his servant.
Faithful: Why, at first I found myself somewhat inclinable to go with the man, for I thought he spake very fair; but looking in his forehead, as I talked with him, I saw there written, “Put off the old man with his deeds.” Then it came burning hot into my mind, that, whatever he said, and however he flattered, when he got me home to his house he would sell me for a slave. So I bid him forbear to talk, for I would not come near the door of his house. Then he reviled me, and told me that he would send such a one after me that should make my way bitter to my soul. So I turned to go away from him; but just as I turned myself to go thence, I felt him take hold of my flesh, and give me such a deadly twitch back, that I thought he had pulled part of me after himself: this made me cry, “O wretched man” [Rom. 7:24]. So I went on my way up the hill. Now, when I had got above half-way up, I looked behind me, and saw one coming after me, swift as the wind; so he overtook me just about the place where the settle stands... But, good brother, hear me out. So soon as the man overtook me, it was but a word and a blow; for down he knocked me, and laid me for dead. But when I was a little come to myself again I asked him wherefore he served me so. He said because of my secret inclining to Adam the First. And with that he struck me another deadly blow on the breast, and beat me down backward; so I lay at his foot as dead as before. So when I came to myself again I cried him mercy: but he said, I know not how to show mercy; and with that he knocked me down again. He had doubtless made an end of me, but that one came by and bid him forbear.
Christian: Who was that that bid him forbear?
Faithful: I did not know him at first: but as he went by, I perceived the holes in his hands and in his side: Then I concluded that he was our Lord. So I went up the hill.
Christian: That man that overtook you was Moses. He spareth none; neither knoweth he how to show mercy to those that transgress the law.
