What does the Bible say about the eternal nature of Christ's substitution?

The eternal nature of Christ's substitution is a profound truth presented in Scripture. Hebrews 7:22 notes that 'Jesus has become a surety of a better covenant,' indicating His role as the substitute was established before the foundation of the world. This means that God, in His sovereignty, ordained Christ as the Redeemer and protector of His elect even before they were created. Such a truth underscores the security of salvation, as it emphasizes God's eternal purpose and grace in providing a Savior. As believers, we can find great comfort and assurance in knowing that our substitute was chosen and appointed from eternity, guaranteeing our acceptance and justification in God's sight.
