What does the Bible say about the perfection of Christ's salvation?

Scripture reveals that Christ's work on the cross was the fulfillment of God's eternal plan for salvation, as seen in passages like Romans 8:32, where it states that God spared not His own Son but freely gave Him for us all. This perfect atonement satisfies divine justice and provides complete remission of sins for those whom Christ died, as stated in Hebrews 10:12, 'But this man, after he had offered one sacrifice for sins forever, sat down on the right hand of God.' Because of His perfect, sinless nature, and His role as the ultimate sacrifice, His resurrection also assures believers that sin has been fully dealt with and thereby provides a perfect salvation.
