How does Tom try to avoid fulfilling his end of the bargian?
As Tom grew older, and gained more money than he knew what to do with, he began to grow nervous that the devil would return to collect his end of the bargain. To keep the devil at bay, he begins going to church. He prays loudly, and outwardly appears to have become the picture of a good Christian soul.
He became, therefore, all of a sudden, a violent church goer. He prayed loudly and strenuously as if heaven were to be taken by force of lungs. Indeed, one might always tell when he had sinned most during the week, by the clamour of his Sunday devotion.
His new outlook was noted by the other people in the town who were surprised that this new member of the church seemed to be more religious than them.
The quiet christians who had been modestly and steadfastly travelling Zionward, were struck with self reproach at seeing themselves so suddenly outstripped in their career by this new-made convert.
In fact, Tom treated church the same way he treated his money. In order to lie to himself he would keep track of the people's transgressions and decided for each sin they committed, he was that much better of a person.
Tom was as rigid in religious, as in money matters; he was a stern supervisor and censurer of his neighbours, and seemed to think every sin entered up to their account became a credit on his own side of the page. He even talked of the expediency of reviving the persecution of quakers and anabaptists. In a word, Tom's zeal became as notorious as his riches.
Of course, none of this mattered. His new ways did not show a change in heart. He would still make bad deals, he would just read the bible while he did so. In the end, the Devil returns and takes away Tom and he is never seen again.
