How does Jesus' sacrifice relate to our forgiveness?

The suffering and crucifixion of Jesus are central to the Christian understanding of forgiveness. As stated in Hebrews 10:10, 'we are sanctified through the offering of the body of Jesus Christ once for all.' This act of substitution—where Christ, who knew no sin, became sin for us (2 Corinthians 5:21)—allows believers to be seen as righteous before God. The once-for-all nature of His sacrifice means no further offerings are necessary, assuring us that our sins are fully paid for, presenting us complete before our Holy God.
