“For with a strong hand the LORD has brought you out of Egypt” (v39). The Passover helped the Israelites remember their history: that God saved them from slavery “with a strong hand” to bring them to “a land flowing with milk and honey” (v3,5). Their trust and obedience, going forward, was to flow from knowing God’s character: He was the One who rescued them to give them a better life.
“And the Lord went before them by day in a pillar of cloud … and by night in a pillar of fire” (v21). Like the Israelites, we can follow God into the unknown only if we are convinced that He is on our side - our Helper, our Savior.
