How does substitution relate to God's eternal plan?

Substitution is at the heart of God’s eternal plan, first established before the foundation of the world when Christ was designated as the Lamb slain for His people (Revelation 13:8). This theological perspective conveys that God’s sovereign choice and redemptive plan are intentionally woven through the narrative of Scripture—from the sacrifices in the Old Testament to the ultimate sacrifice of Christ. Christ’s substitutionary death fulfills the type and shadow of the Old Testament sacrifices, bringing to fruition the promise of redemption. Such a paradigm directs believers to the understanding that our salvation was meticulously planned and executed by God who, in His sovereignty, determined the means by which His elect would be saved through the blood of Christ.
