Sin is defined in three main views: (1) Biblical view that sin originated from humanity's free will to disobey God and was permitted by God for His glory, (2) Wrong views that see sin as inevitable, eternal, or that absolve God of responsibility, and (3) Common excuses that downplay sin such as seeing it as humanness, a disease, or ignorance. The document examines each of these views of sin and their implications to understand sin from a biblical perspective.
