How do we know that Christ's sacrifice satisfies God's justice?

The assurance that Jesus' sacrifice was satisfying to God is found in His resurrection and ascension. Romans 8:33-34 articulates that it is 'Christ that died, yea rather, that is risen again,' affirming that the Father accepted the sacrificial work of the Son. This completion of the atonement illustrates not only the efficacy of Christ's death but His current role as intercessor. As the God-man mediator, He bore the penalty of sin for the ungodly, satisfying the demand of God's holy law and declaring those who believe righteous.
