It's a puritanical thought process. Puritans were not very happy and I think there is still a great influence on fundamentalist Christians today. I've added a link and a few paragraphs.
http://www.nd.edu/~rbarger/www7/puritans.html Each church congregation was to be individually responsible to God, as was each person. The New Testament was their model and their devotion so great that it permeated their entire society. People of opposing theological views were asked to leave the community or to be converted.
Their interpretation of scriptures was a harsh one. They emphasized a redemptive piety. In principle, they emphasized conversion and not repression. Conversion was a rejection of the "worldliness" of society and a strict adherence to Biblical principles. While repression was not encouraged in principle, it was evident in their actions. God could forgive anything, but man could forgive only by seeing a change in behavior. Actions spoke louder than words, so actions had to be constantly controlled.
The doctrine of predestination kept all Puritans constantly working to do good in this life to be chosen for the next eternal one. God had already chosen who would be in heaven or hell, and each believer had no way of knowing which group they were in. Those who were wealthy were obviously blessed by God and were in good standing with Him. The Protestant work ethic was the belief that hard work was an honor to God which would lead to a prosperous reward. Any deviations from the normal way of Puritan life met with strict disapproval and discipline. Since the church elders were also political leaders, any church infraction was also a social one. There was no margin for error.
The devil was behind every evil deed. Constant watch needed to be kept in order to stay away from his clutches. Words of hell fire and brimstone flowed from the mouths of eloquent ministers as they warned of the persuasiveness of the devil's power. The sermons of Jonathan Edwards, a Puritan minister, show that delivery of these sermons became an art form. They were elegant, well formed, exegetical renditions of scriptures... with a healthy dose of fear woven throughout the fabric of the literary construction. Grammar children were quizzed on the material at school and at home. This constant subjection of the probability of an unseen danger led to a scandal of epidemic proportions.
