What does the Bible teach about the nature of sin?

The Bible presents sin as a fundamental separation from God, inherent to humanity since the fall. Romans 8:7 describes the carnal mind as being enmity against God, illustrating the natural disposition of unregenerate hearts that rebel against God's authority and righteousness. This enmity reflects humanity's deep-seated rebellion and self-righteousness, which cannot meet God's standards. The Scripture consistently emphasizes that sin results in death and serves as a reminder of humanity's desperate need for redemption, which can only be found through faith in Christ's atoning sacrifice. Understanding sin's nature highlights the necessity for grace and the transformational power of the gospel, guiding believers toward repentance and reconciliation with God.
