The Greek word for sin is hamartia, and the word for knowledge is ology. Therefore, hamartiology is the knowledge of the doctrine of sin. The scriptures speak continuously of the presence and reality of sin in the world. From Adam’s first sin through the final chapters of Revelation, God speaks of man’s sin and sinful nature. In the Old Testament, we read: “For there is not a just man on earth who does good And does not sin” (Ecclesiastes 7:20). Paul said, “THERE IS NONE RIGHTEOUS, NO, NOT ONE” (Romans 3:10); “For all have sinned and fall short of the glory of God” (Romans 3:23).
