The concept of sin and separation is central to understanding the theological implications of Jesus' sacrifice. Sin, as defined within Christian doctrine, represents a fundamental breach in the relationship between humanity and God. This separation is not merely a transactional issue but rather a relational one, where sin creates a chasm that alienates individuals from their Creator. The narrative of sin begins with the Fall in Genesis, illustrating how disobedience to God's command led to estrangement and the introduction of death into the world. This foundational story sets the stage for the necessity of redemption, highlighting the weight of sin and its pervasive impact on human existence.
