Calvinism teaches that all human beings possess evil desires, which are suppressed through domesticating influences such as laws and social norms, and unleashed when these influences are removed. ‘Humanity and new humanity’ explains that the idea of original sin—the result of the fall of Adam and Eve—has deeply impacted the Reformed tradition. Although Calvinists agree that Adam’s sin affected all his descendants, they explain the transmission of his sin in different ways. Both the restraining of sin and the escape from enslavement to sin are things Calvinists explain by pointing to the idea of grace. Having become a Christian, the convert lives a new life in covenant relationship with God where prayer is essential.
