What is defined as God’s act of freeing His people from sin?

The correct answer is redemption, which is defined as God's act of freeing His people from sin. In the context of Christian theology, redemption signifies the process through which humanity is liberated from the bondage of sin and its consequences. This concept highlights the sacrificial work of Jesus Christ, who, through His death and resurrection, accomplished the necessary means for believers to be set free from the guilt and power of sin.

Redemption encompasses not only the forgiveness of sins but also the restoration of believers to a right relationship with God. It is essential to understand that this act is seen as a fundamental aspect of God’s grace, reflecting His desire to bring His people back to Himself, thereby affirming both His justice and mercy.

While justification is concerned with the declarative aspect of being made right before God, and sanctification involves the process of growing in holiness after redemption, it is redemption itself that directly addresses the freeing from sin. Propagation does not pertain to the concept of salvation or freedom from sin, which further clarifies why redemption is the accurate choice in this context.
