In his sermon, Dr. Harder explains that in Exodus, God sent plagues on Egypt to free the Israelites from slavery and reveal that He alone is the one true God. The tenth and final plague was the death of all firstborn sons, but God provided a way of escape – placing lamb’s blood on their doorposts so the angel of death would “pass over” them. Dr. Harder connects this to the gospel, explaining that like the Passover lamb, Jesus’ blood saves us from God’s judgment and wrath. Just as the Israelites had to follow God’s instructions to avoid the plague, we must follow God’s instructions to find forgiveness and life through trusting in Christ’s sacrifice on our behalf.
