Just as the living Father sent me and I live because of the Father, so the one who feeds on me will live because of me. "This is the bread that came down from heaven. Your ancestors ate manna and died, but whoever feeds on this bread will live forever.”
We are totally dependent on the Lord Jesus. This is why the story of the cross is so central to our faith. There are churches where the cross is barely mentioned, indeed it is a bloody embarrassment. The 'other bread' they are fed includes social work, feeding the hungry, healing the sick, aiding the poor, helping the political underdog. All these are good things but they are not fundamental to the faith. I often ponder that in the new heaven and the new earth they will not need doctors. Or missionaries.
The main thing is the cross. Keep it the main thing.
