How do we know that Christ forgives our sins?

The assurance of forgiveness through Christ is grounded in His sacrificial death and resurrection, which fulfills the requirements of God's law for atonement. In Matthew 9:12-13, Jesus explains that He came to call sinners, not the righteous, emphasizing His mission to provide grace and mercy to those who are lost in sin. Additionally, passages such as 1 Peter 1:3 confirm that believers are 'begotten unto a lively hope by the resurrection of Jesus Christ,' signifying that through His life, death, and resurrection, we are assured of the forgiveness and cleansing from sin. This demonstrates that forgiveness is not based on our merit but solely on Christ's finished work on the cross.
