The tenth plague - the death of the firstborn - serves as a shocking yet profound illustration of God's justice and mercy. We're challenged to see beyond our modern sensibilities and understand the deeper spiritual truths at play. The Passover lamb, with its shed blood marking the doorposts, becomes a powerful symbol pointing directly to Christ. This event isn't just ancient history; it's a blueprint for our own salvation. We're reminded that our rescue from God's judgment comes not through our own efforts, but through the blood of the Lamb.
