“We are were redeemed with the precious blood of Christ, a lamb without blemish or defect.”
1 Peter 1:19
Jesus is pictured with crystal clarity in the Passover (Exodus 12).
God’s judgment on Egypt was set. God planned to kill the firstborn of every family (a picture of all in every family). God promised to spare those who, in faith, sacrificed an innocent lamb, and who put its blood on the doorposts and lintels of their houses. When God went throughout the land taking the lives of the firstborn, the Lord “passed over” the homes marked by the blood (Exodus 12:23).
Can you see that this is a picture of Christ Jesus, the ultimate, innocent Lamb of God who shed His blood on the cross? All who, in faith, are under the blood of Jesus will be “passed over” in the last Judgment. How is that possible? Jesus shed His innocent blood: (1) to pay the penalty for our sins; and (2) to purchase our release from bondage to sin.
We receive that incredible blessing by trusting in Christ by “getting under His blood.” (1 Peter 1:19)
In the same way the Jews did nothing to deliver themselves, and contributed nothing to what God did for them, we do nothing to save ourselves, and contribute nothing to what God in Christ has done for us.
As the Jews were to escape from Egypt, fleeing to the Promised Land, though we live in this world, we flee the world by refusing to be worldly. And just as the Jews were to celebrate the Passover to remember God’s gracious deliverance from Egypt, we celebrate the Lord’s Supper to remember God’s gracious deliverance from sin, death, and Hell.
