When he sees the blood on the lintel and the two doorposts, God will pass over the doorway; he won't let the destroyer enter your house to strike you down with ruin. Exodus 12:23 (MSG)
Many years ago some friends came over and prepared a Passover meal to celebrate with my family. To this day, I remember how blown away I was as we went through the ritual of the meal. There were so many parts of the story and the meal that, metaphorically, point directly to Jesus, who would arrive centuries later.
I love the way God's message fits together. As I read about the blood of the lamb covering the doorposts of the Israelites and Death "passing over" those who were covered by the blood of the sacrificed lamb, I can't help but think of Jesus, the Lamb of God, who came to take away the sins of the world. Jesus, the sacrificial Lamb whose blood covers us and swallows up Death through the power of His resurrection.
I've known many people who avoid reading the Old Testament because it's not always easy to connect the history to our lives today, But, without the story of the Passover, it's hard to fully appreciate the depth of who Jesus was, nor the way God's plan is woven through history.
