A Week That Changed the World: Thursday, Part 2: In the Passover, the Jewish people were to take unleavened bread.  However, as soon as they arrived in the Wilderness, God provided Manna.  In John 6, Jesus introduced Himself as the Manna from Heaven, the Bread of Life. Then, at the Last Supper, Jesus took leavened bread--not unleavened--and created a new and unique observance for believers, not based on the passover, but on the Manna from Heaven.
