Exodus 12:12-14 (CEB)
12I'll pass through the land of Egypt that night, and I'll strike down every oldest child in the land of Egypt, both humans and animals. I'll impose judgments on all the gods of Egypt. I am the Lord. 13The blood will be your sign on the houses where you live. Whenever I see the blood, I'll pass over you. No plague will destroy you when I strike the land of Egypt.
14"This day will be a day of remembering for you. You will observe it as a festival to the Lord. You will observe it in every generation as a regulation for all time.
When Jesus came to Jerusalem, in the week before his crucifixion, it was during the Passover festival. This was a huge celebration for the Jewish people.
In the days of Moses, the Israelite people were being held captive in Egypt. God had been working through Moses to convince the Pharaoh to release them. God had sent major plagues against the Egyptians: all the water in the land turned to blood; the countryside teamed with frogs; locusts came and devoured all the vegetation; and there were many others. But Pharaoh refused to let the people go.
After numerous plagues and numerous warnings from Moses, a final plague came that killed all the firstborn throughout the land of Egypt. To protect the Israelites, God instructed each family to sacrifice a lamb and smear its blood on the doorframe of their house. The plague would "pass over" the houses of everybody who followed God's command. The next morning, Pharaoh released the Israelites.
It's fitting that the meal Jesus was sharing with his disciples during the Last Supper was the Passover meal, because Jesus became our Passover lamb. One day, when this life is over, we'll all stand before God for judgment. We are all sinful and will all be judged ineligible for eternal life in Heaven. But, because of Jesus' sacrifice, that judgment will "pass over" us and we'll join him in Heaven forever.
If you don't feel as though you have a good relationship with Jesus--if you don't quite understand what he's all about--make a plan to learn more. Attend Sunday school. Read your Bible. Ask your youth leaders or pastor to help you understand anything that doesn't make sense. Pray more often.
If today's devotion spoke to you in a particular way and you feel led to share your thoughts with others, please do so.
