How do we know the doctrine of satisfaction is true?

The doctrine of satisfaction is founded on the belief that Christ's death fully satisfied the just demands of God against sin. In the sermon, it is emphasized that upon His death, God tore the curtain in the temple from top to bottom, symbolizing the removal of the barrier between humanity and God due to sin. By paying the penalty for sin, Jesus Christ, as the perfect sacrifice, met the requirements of God's justice. This fulfillment of divine justice assures us that salvation is complete and hinges not on our efforts but solely on Christ's finished work.
