The tenth plague, the death of the firstborn, introduces Passover, so named because the angel of death passed over homes protected by the blood of a lamb smeared across the doorframe. God told the Israelites to smear the blood.
But God knew which homes belonged to Egyptians and which were Israelites. Why didn’t he simply skip the Israelite homes? Why did God require blood on the doorframe of a house to protect it from death?
Go back to the beginning of the book. The very beginning, the first two chapters of Genesis. When Adam and Eve chose their own desires rather than God’s, they chose death. Judgment was immediate and they were instantly severed from God. They were, therefore, dead, because God is life, and this has been passed on to each and every one of us. We are all dead, separated from God because of sin. But, at the same time, grace came alive. God allowed Adam and Eve, though dead, to keep breathing, and he launched his plan of salvation.
Fast forward to Exodus 12. The judgment that would be passing through the land that night was just. Every family deserving of death would be visited by the destroyer, and every family deserved death, including the Israelites. That Passover night, the destroyer would be indiscriminate. Egyptian or Israelite, all would be visited, unless death had already visited that household. A substitute had been sacrificed, a lamb approved by God had paid the price. Blood on the doorframe was a sign that the sins of this household had been covered by the death of a lamb.
Fast forward to A.D. 30. “The next day John the Baptist saw Jesus coming toward him, and said, ‘Behold, the Lamb of God, who takes away the sin of the world!’” (John 1:29) Grace is still alive.
Almighty God, Your goodness runs deep, but I choose to wallow in the shallows of my desires. Still, despite my rebellion, Your grace seeks me through the loving sacrifice of Your Son. Your righteousness consumes my own passions, and my desires become Yours. In response to Your never-ceasing, never-ending love, I live thankfully and joyfully in a world made new again.
What a wonderful Savior. What amazing grace.
