How do we know that God is satisfied with Christ's sacrifice?

God's satisfaction in Christ’s sacrifice is rooted in the theological understanding that Jesus fulfilled every requirement of the law on behalf of His people. In John 17:4, Jesus states, 'I have glorified You on the earth. I have finished the work which You have given Me to do.' This declaration confirms that His mission was completed in perfection, fulfilling God’s justice while providing mercy for the elect. This act of redemption assures believers of their acceptance before God, as Christ’s perfect righteousness is imputed to them, establishing a foundation for their faith and assurance in God’s continual satisfaction with them through Christ.
