Christ is our high priest. He ministers with our names on His heart as the priests in the Old Testament carried the names of the 12 tribes of Israel. They prayed, they offered sacrifices for the people. But they were limited.
The author of Hebrews wrote “it is impossible for the blood of bulls and goats to take away sins. Consequently, when Christ came into the world, he said ‘Sacrifice and offerings you have not desired, but a body you have prepared for me'” (Hebrews 10:4-5). Why a body? Jesus not only offered sacrifices, He was the sacrifice, and many offspring came from His offering (Isaiah 53:10).
[E]very priest stands daily at his service, offering repeatedly the same sacrifices, which can never take away sins. But when Christ had offered for all time a single sacrifice for sins, he sat down at the right hand of God, waiting from that time until his enemies should be made a footstool for his feet. For by a single offering he has perfected for all time those who are being sanctified. (Hebrews 10:11–14)
In the communion meal we come to the epicenter of our life, the epicenter of our sanctification, the epicenter of our victory. Jesus conquered sin, He killed death, He defeated His enemies, and He has returned to glory until that time when He comes to get us and bring us to glory.
He gave His body for the bread of our life. He gave His blood as the covenant of life. He is true food and true drink. He invites us to partake of Him, to share together His love until the glorious day when we will be with Him where He is and see the glory that the Father gave Him in love (John 17:24).
