Exodus 10:2, Tell or recount, relate. YHVH commanded Moses to record the story of Egypt’s judgment and fall for the Israelite’s future posterity. The Israelites were to pass this story down orally and in written form to succeeding generations. The Passover seder is the fulfillment of this Torah command in that it re-enacts the exodus story. In other words, YHVH is commanding parents to pass the gospel message of redemption downward to each new generation. The Passover seder is literally a gospel tract involving a dramatic presentation where the participants act out the message of the gospel.
