Hamartology is the study of sin as understood within Christian theology. The term derives from the Greek word "hamartia," which translates to "sin." In the Bible, sin is portrayed as a fundamental issue that separates humanity from God. Romans 3:23 states, "For all have sinned and fall short of the glory of God," highlighting the universal nature of sin. This doctrine examines the nature, origin, consequences, and remedy for sin, with a significant focus on the theological implications it has for salvation and human existence.The biblical narrative explains that sin entered the world through the disobedience of Adam and Eve in Genesis 3, leading to the fallen state of humanity. This event initiated a profound need for redemption, which is fulfilled in the New Testament through the sacrificial death and resurrection of Jesus Christ (John 3:16; Romans 5:8). Hamartology thus not only addresses the condition of sin but also emphasizes the hope of reconciliation with God through faith in Christ, as articulated in passages like 1 John 1:9, which assures believers that if they confess their sins, God is faithful to forgive them.
