Did Jesus really have to say, "Unless you eat the flesh of the Son of Man and drink his blood, you have no life in you," (John 6:53)?
His description startles us! But, we need to be shaken out of our slumber. Our proclivity toward spectating in worship is strong. In fact, given our entrainment and celebrity culture, this tug threatens to undermine the church's highest calling: worship the One, True, and Living God!
Real worship arouses us out of spectating and invites us to commune with Jesus.
The invitation to feast on the Son of Man came soon after Jesus walked on water. Like turning water to wine, healing the blind, and raising people form the dead, our sin nature turns these events and Jesus' himself into something to watch and marvel from afar without engaging Him in a relationship. We turn him into a performer when He has come to be our Passover Lamb.
The Lord's Supper, like baptism, gets us involved. Whereas baptism speaks of WHO we are in Jesus, the Lord's Supper speaks of WHERE we are with Jesus -- we are reclining at the Table with our Lord! He has come "making peace, and [reconciling] us both to God in one body through the cross, thereby killing the hostility" (Ephesians 2:15-16).
Therefore, let us keep the feast!
