How do we know that Christ's victory over sin and death is true?

The reality of Christ's victory over sin and death is rooted in the historical event of His crucifixion and resurrection. In the sermon, it is emphasized that through His death, Jesus has defeated every enemy of our souls, including sin, Satan, and death itself. The assurance of salvation stems from God's promise that He has put away the sins of His people, stating, 'Your sins and your iniquities will I remember no more.' The resurrection of Christ serves as the ultimate confirmation of His victory, proving that death cannot hold those who belong to Him. This victory provides comfort and assurance to believers, affirming that all things are being worked for their good according to God's eternal purpose.
