27 Then he took the cup, and when he had given thanks, he gave it to them, saying, "Drink from it, all of you. 28 This is my blood of the covenant, which is poured out for many for the forgiveness of sins. 29 I tell you, I will not drink of this fruit of the vine from now on until that day when I drink it new with you in my Father's kingdom."
Jesus told his shocked disciples and would be followers in another place that unless they ate his flesh and drank his blood they would have no life in them (John 6:53). Even though that passage reminds us of the Last/First Supper, I think in context it means and certainly involves what it means to be a true follower of Jesus. It is metaphorical for living on the basis of who he is and what he has done for us, a living that is by faith in following.
We follow Jesus by feeding on him and we also feed on Jesus by following him. We taste more and more of who he is as we seek to follow on in this life and like the disciples of old, doing so together or bringing others along with us. We more and more lose our old apetites as we learn to eat and drink of Jesus. And this is meant to be celebrated and lived out together with Jesus.
This means I can be happy (or learn to be) abstaining from some old feastings which really are either not of God or are not for me at a particular time. That is because I've caught a new aroma and have a new taste for something so much better that replaces death with true life. Instead of the living death I used to live, it can be more and more a dying (in Jesus) life.
This is intensely personal and yet must become intensely communal as well. In nature it is communal in that this partaking is to be together with our Lord as we see over and over again in Scripture. But each of us must do this, making it a part of our daily lives as followers of Jesus.What might you add and/or what helps you "feed on Jesus"?
