What did the Israelites know by faith about the blood on the door?
The Israelites, by faith, knew that the blood on the door posts kept them secure, so the death angel would not strike them. Because the blood was there, they were safe and secure and did not have to shake with fear all that night.
Les teaches that the Jewish families stood in their hovels around the kitchen table with the Passover lamb roasted, partaking of it for strength for their journey. He emphasizes that when they knew the blood was out there on the door post, they did not shake with fear all that night. Why? Because by faith they knew the blood had kept them secure. They knew by faith that with the blood on the door, the death angel would never strike them. They were safe and secure and did not have to shake in their boots. Les then connects this to Paul in Romans, reminding that Christ was our Passover, and if there is a Passover lamb, there must be blood, because the whole idea was the shedding of the lamb's blood that it could be stricken on the door post.
