The Lord’s Supper is a sacrament that nourishes believers with the benefits of Christ’s once-for-all sacrifice.  We need to see and believe that we serve a risen and present Savior. Christ’s sacrifice is not repeated, but a spiritual meal where the Holy Spirit strengthens our faith.  Christ invites us to do this in remembrance of him, not as an empty memorial.  We think of the memorial stones set up by Israel, where they recognize the continual care, protection, and presence of their God with His people. So, we evaluate whether the truth of our faith, where we are grounded, and continue to seek our life in Christ.  Ultimately, this sacrament pictures for us that our Lord continues to nourish, protect, and lead us to the heavenly banquet.
