What does it mean that Jesus was foreordained before the foundation of the world?

1 Peter 1:19-20 reveals that Jesus was 'foreordained before the foundation of the world' to be the sacrificial Lamb for humanity's sins. This doctrine confirms that God’s plan for salvation was established in eternity past, affirming His sovereignty and the certainty of redemption. It underscores the significance of Christ's sacrifice, not as a reactive measure after the fall, but as a deliberate provision in God’s eternal purpose to redeem His people, reflecting both His justice and unparalleled grace.
