“‘The blood shall be a sign for you on the houses where you live; and when I see the blood I will pass over you, and no plague will befall you to destroy you when I strike the land of Egypt. ” (Exodus 12:13, NASB95)
Obviously, this is a key verse from the Passover story. I find it very interesting that God made no separation/distinction between Egypt and Israel for the 10th (and most deadly) plague. God was going to cause the firstborn of all living in Egypt to die unless the Passover requirements were followed and the blood of the lamb was put over the doorpost of the house. Only the blood of the lamb would cause the angel of death to pass over the house. Even the children of Israel would fall victim to this plague if they failed to follow the passover requirements.
God required the Jews to celebrate the Passover annually in remembrance of their deliverance from slavery and death by His grace and through the blood of the lamb. Today, Christians celebrate their own Passover every time they take communion. We, too, have been delivered from slavery and death by God’s grace and the blood of the Lamb. There is no separation or distinction. One cannot escape death without believing in Jesus and applying His blood which washes away all our sins. Every time you see a cross/crucifix you should be thinking about your own Passover.
In reality, we have the privilege to celebrate our passover every day as we live under the shadow of the cross.
