In Christian theology, the passage of an individual from sin to a state of grace. Some theologians use the term to refer to the act of God in extending grace to the sinner, while others use it to define the change in the condition of a sinner who has received grace. St. Paul used the term to explain how people moved from sin to grace through the death and resurrection of Jesus and not through any human effort. St. Augustine saw it as an act of God that makes sinners righteous, while Martin Luther stressed justification through faith alone.
