The Pesach Haggadah is a study in striking contrasts. On the one hand, we begin by bemoaning sordid origins as idol worshippers. On the other hand, we celebrate the miraculous redemption from Egypt and slavery.

We are most grateful for all of the good G-d does for us. Lest there be any doubt, we sing Dayenu, which makes it clear that it would have been sufficient even if G-d merely took us out of Egypt, let alone all the miracles that occurred, including bringing us to Israel and building the Beit HaMikdash

We are obligated, in every generation, to visualize ourselves as if we were there too exiting Egypt, as a part of the miraculous redemption, for the purpose of bringing us to and vesting us in the Promised Land of Israel. This is even more meaningful in our times, as we are ever so thankful that the prophesized redemption has begun, with the miraculous recreation of the modern State of Israel.
