This is a lesson about justification, sanctification, and grace. It emphasizes that being "nice" is not enough; the goal is to become holy, which requires God's grace. The lesson defines and explains different types of grace, including sanctifying grace, actual grace, and sacramental grace. It also clarifies the difference between human virtues and supernatural virtues, particularly the theological virtues (faith, hope, and charity) and the cardinal virtues (prudence, justice, fortitude, and temperance).
