What does it mean that God 'passes through' to strike? How does judgment and mercy intersect in this moment?
This verse reveals a profound truth about God's actions. He is the one who brings the devastating plague upon Egypt. The language 'pass through to smite' indicates His active, sovereign judgment on a nation steeped in sin. Yet, within this same act of judgment, God provides a way of escape. His 'passing over' the houses marked with blood isn't a passive avoidance, but a deliberate act of mercy. It shows God's justice and His grace are not in opposition but are perfectly united in His plan. He judges sin, but He also provides a Redeemer.
