This meal is a covenantal meal. Jesus said specifically: this cup is the new covenant in His blood. A covenant is a real, personal relationship, sealed in blood, with blessings and curses attached to it. Keeping covenant results in blessings while breaking covenant hauls out the curses.
But how do we keep covenant? How do we embrace the blessings and flee the curses of the covenant? The Bible says that we keep covenant by faith. The just live by faith. This is the work that God requires of us: to believe on Him whom He has sent. Jesus has kept covenant perfectly. He obeyed His Father perfectly, He obeyed even in the face of injustice, in the face of shame and pain and suffering, He entrusted Himself to the One who judges justly. And God raised Him from the dead on the third day.
This is what faith does: Faith looks at sin, at brokenness, at hurt, at shame, at pain and then looks to Jesus crucified and risen. Faith sees in Jesus, in His death and resurrection the promise of God to put all things right. Are you a failure? Have you sinned? Have you let others down? Have you been hurt? Have you been stabbed in the back? Are you facing sickness, pain, confusion, death? Jesus died with you in mind, with your circumstances in mind. And God raised Him up with you in mind, with your whole life in view.
This table is for those hungry for glory and beauty, for those who are not satisfied with the status quo, who will not make peace with sin or brokenness or death in any form. So place your trust in Jesus. He is your glory and beauty.
