In Exodus we have the account of God delivering His people from slavery in Egypt. As an act of judgment God announced that the firstborn son of every family and flock in Egypt would be killed – but He made a way of safety for His people. He instructed them to kill a lamb and put the lamb’s blood on the doorpost of their home. Every home that was covered with the blood of a lamb would be passed over. While God’s act of salvation was extraordinary, He knew the people would still be quick to forget. For this reason, He commanded them to keep an annual feast. This feast, which involved sacrificing a lamb, would be a means of remembering God’s salvation in the past and anticipating His future salvation. And it’s a feast that was still held every year during the time of Jesus. Each year His parents would travel to Jerusalem to celebrate Passover (Luke 2:41). It’s of no small significance that on the night before His death Jesus celebrates a Passover meal with His disciples. During that meal Jesus demonstrates His sovereignty, announces His death, institutes a new meal for people of God and promises a future meal that’s still to come.
