Have you ever asked why something is done the way it is? How many times has the answer been, “That’s just the way it’s always been done”? Truth be told, that isn’t a satisfactory answer because it gives no resolution. As we watch the tenth and final plague unfold, we see God institute new customs into the lifeblood of Israel. As God instructs Israel in the celebration of the Passover, He tells them why: to remember that it was God who delivered; He did the unthinkable and saved them from their slavery. Remembering this truth would sustain them for years to come. God knows where we focus our time and energy. The things we celebrate shape our hearts, minds, and actions. God wanted His people to be marked by their dedication to remembering His faithfulness to His promise throughout all the generations, for their good and His glory.
