Dr. W.A Criswell was a well known preacher and pastor of the Southern Baptist Convention several decades ago. He preached a sermon and wrote a book entitled, “The Scarlet Thread Through the Bible.” In this Christian masterpiece, he referenced the numerous places in Scripture that have a clear reference to the plan of redemption through Christ’s blood, starting all the way back in the book of Genesis and continuing on through the book of Revelation.
In our reading today, we are able to read one of the Old Testament passages that allow us to see this “scarlet thread”. Most of us, no doubt, are very familiar with the story of the 10 plagues that God used to judge Egypt and allow His people to escape their bondage. In Exodus 11 we read about the final plague, that being the death of the firstborn child in every home (probably the firstborn male child). However, there was one way to escape the death angel on that particular night. The Jewish people were instructed to take the blood of a lamb and “strike it on the two side posts and on the upper door post of the house.” As long as a family would do as they were instructed, all would be safe in that house, including the firstborn. Imagine the hysterical cries that went up throughout the land of Egypt that night as parent after parent found their oldest child dead. Yet for those who followed the clear command of God and had the blood applied to the doorposts, there was safety and security. Clearly, this is a very clear and wonderful picture of salvation and brings to mind the familiar hymn, “When I See the Blood”. Think about the first verse of that song, “Christ our Redeemer died on the cross,Died for the sinner, paid all his due; Sprinkle your soul with the blood of the Lamb, And I will pass, will pass over you.” What a wonderful song and truth! How about you today, has the blood of Christ been applied to the doorpost of your heart? It truly is our only hope of salvation!
