Tenth Plague: Saved by the Blood Exodus 12:1-13;14-28 These events revealed God’s plan and shaped our understanding of the gospel. Remembering that God Delivers through the Passover and the Lord’s Supper. Israel was in Egypt 430 years, but God delivered them. Our God keeps His promises. Their faith, or belief, in the word of God through Moses is what led them to apply the blood to their doorposts. And that faith, represented by the visible blood, is what caused them to be “passed over.” Applied blood was only a sign of applied faith. The blood on the doorposts showed acceptance of God’s plan for rescue and trust in his word. After all, the sight of dried blood by itself had no power to deter death; it was only as the dried blood painted on the top and sides of the door was a testimony to their faith.
