How do we know Christ's death accomplished our redemption?

The accomplishment of our redemption through Christ's death is foundational to the Gospel message. In John 17:13, Christ emphasizes the joy that believers find in knowing that His death would deliver them from their sins. Hebrews 10:14 further clarifies this truth, stating, 'For by one offering He has perfected forever those who are being sanctified.' This means that through Christ's sacrificial death, He has effectively dealt with the penalty of sin, securing a complete and perfect redemption for all who believe in Him. His resurrection serves as confirmation that this redemptive work is finished, demonstrating that believers are justified and eternally reconciled to God.
