How do we know God provided a sacrifice for sin?

God's provision of a sacrifice for sin is a recurring theme throughout Scripture, reaching its apex in Jesus Christ. Genesis 22:8 records Abraham's prophetic declaration, 'God will provide Himself a lamb.' This foreshadows the coming of Jesus, who is the Lamb of God offered for humanity’s sins (John 1:29). Furthermore, the prophetic nature of sacrifice is reinforced in the New Testament where Jesus fulfills the role envisioned in the Old Testament, stating in Matthew 26:28, 'For this is my blood of the covenant, which is poured out for many for the forgiveness of sins.' This continuity between the testaments illustrates God's unwavering commitment to provide a means of reconciliation for His people.
