Exodus 12:7 "Then theyare to take some of the blood and put it on the sides and tops of the doorframes of the houses where they eat the lambs. (The Lord tells Moses what he is to instruct God's people to do to be protected from the coming judgment on Egypt. He gives specific instructions for the people's protection. They do not get to choose what part of God's instructions they will follow or how they will apply God's provision. His instructions are precise. Neither do we get to choose which of the Lord's specific instructions to follow or how we will apply His provision through Christ for us. There is no other way to salvation except through His provision, and His way is perfect and complete. The tops of the doorframes is a phrase referring to a small window that allowed inhabitants to look out and see who was at their door. When we apply the blood of the Lamb to the doors of our lives, we can safely remain inside His protection and discern who or what is at the door and whether a friend or foe. Just as the entry door of their home had to be marked with the lamb's blood, so the door of our lives, our hearts, our souls, have to be marked with Christ's shed blood. As a substitution for the life of the firstborn of Egypt, Israelites were granted the exchange of the blood of a lamb for their lives. We are also welcomed to the atonement, the replacement of our punishment with His rescue and salvation that the Lamb of God has provided for us today.)
