"I will take you as my own people, and I will be your God. Then you will know that I am the LORD your God, who brought you out from under the yoke of the Egyptians." Exodus 6.7
The cup we share at Communion has its origin in the ancient Jewish festival of Passover. Passover celebrates how God liberated his chosen people from slavery in Egypt, passing over their homes which were daubed with the blood of sacrificed animals, while he exacted the terrible judgment on Egypt to enable the Jews' escape. Observing the feast as his last meal with the disciples, Jesus invested it with a new meaning to signify the greater liberation which he was now securing through his own blood: freedom from slavery to sin - for his Jewish compatriots and for the whole world. Every time we receive the bread and wine of Communion we acknowledge our enjoyment of the fruits of Jesus' sacrifice and God's blessing.
