How do we know that Jesus is the substitute for believers?

The death of the firstborn during the final plague in Exodus serves as a foreshadowing of Christ's sacrificial death. Just as the Israelites placed the blood of a lamb on their doorposts to be spared from judgment, Jesus, referred to as the Lamb of God, provides redemption for His people through His death. This provision of a substitute highlights God's merciful plan for salvation, showing that even in judgment, He offers a path to escape through faith in Christ. The imagery of the Passover continues to resonate throughout scripture, culminating in the New Testament where Christ's death secures eternal life for all who believe.
