my favorite passage from the Haggadah this Passover:
11. Enjoyment of the Festival Meal
Leader: Let us now take time to enjoy the festival meal. We will begin with the roasted egg, a reminder of the final destruction of the Temple in 70 AD and the end of a place for the sacrifice...
As we eat this egg as our "fellowship offering" let us offer our lives as living sacrifices to the God we serve and follow. To remind us that the joy of sacrifice may be surrounded by tears, we dip the egg into the salt water before us.
All: Blessed are you, O Lord our God, who turns our mourning into dancing.
