1. Passover is what God told the Israelites to do when they left Egypt. Because there is an angel who wants to destroy all the firstborn, whether human or livestock. As long as you kill a non-disabled sheep, wipe the blood off the lintel and door frame with hyssop, and the killing angel will pass the blood when he sees it. The angel only looked at the blood on the lintel and doorframe, but didn't look at what the people in the house were doing. Anyone who has no sheep's blood on the lintel and door frame, regardless of good or evil, will be beheaded.
2. Passover lamb refers to Jesus. We should have been cursed and perished in sin, but God's love came to us. God sent his son Jesus Christ into the flesh and crucified him for our sins. John 1:29 The next day, John saw Jesus coming to him and said, "Look, the Lamb of God takes away the sin of the world.
No matter what sins we committed before or after, when we really accepted the blood of the cross of Jesus and washed away all our sins, we were freed from all curses and deaths. For the blood of Jesus was shed for us, and the body was laid down for us, so that our sins could be forgiven. Thank God for his grace. Glory to God.
