The crucial test of the divineness of the work was given when the people presented themselves before the Lord with a solemn act of thanksgiving for his great goodness and his gracious presence in the town of Northampton, with publicly recorded vows to renounce their evil ways and put away their abominations from before his eyes. They solemnly promise thenceforth, in all dealings with their neighbor, to be governed by the rules of honesty, justice, and uprightness; not to overreach or defraud him, nor anywise to injure him, whether willfully or through want of care; to regard not only their own interest, but his; particularly, to be faithful in the payment of just debts; in the case of past wrongs against any, never to rest till they have made full reparation; to refrain from evil speaking, and from everything that feeds a spirit of bitterness; to do nothing in a spirit of revenge; not to be led by private or partisan interest into any course hurtful to the interests of Christ's kingdom; particularly, in public affairs, not to allow ambition or partisanship to lead them counter to the interest of true religion. Those who are young promise to allow themselves in no diversions that would hinder a devout spirit, and to avoid everything that tends to lasciviousness, and which will not be approved by the infinitely pure and holy eye of God. Finally, they consecrate themselves watchfully to perform the relative duties of parents and children, husbands and wives, brothers and sisters, masters, mistresses, and servants. So great a work as this could not be hid. The whole region of the Connecticut Valley, in Massachusetts and Connecticut, and neighboring regions felt the influence of it. The fame of it went abroad. A letter of Edwards's in reply to inquiries from his friend, Dr. Colman, of Boston, was forwarded to Dr. Watts and Dr. Guise, of London, and by them published under the title of "Narrative of Surprising Conversions." A copy of the little book was carried in his pocket for wayside reading on a walk from London to Oxford by John Wesley, in the year 1738. Not yet in the course of his work had he "seen it on this fashion," and he writes in his journal: "Surely this is the Lord's doing, and it is marvelous in our eyes."
