The 6th chapter of John
is very much about eating. Jesus presents Himself as the true bread that came down from heaven. In other words the manna
that came down upon the Israelites in the wilderness for forty years was a symbol of Christ.
Christ is the true "food" from God out of heaven. What we eat becomes a part of our being. We are constituted from all the food stuff that we eat. God wants to work Christ into His chosen and redeemed people. So He feeds them with Christ who gets into them. saturates them, constitutes them, and builds Himself into the "fabric" of their whole being.
The reality that He experienced as a man is a model of the same path which all His believers must walk in.
"As the living Father sent Me and I live because of the Father, so he who eats Me, he also shall live because of Me.
This is the bread which came down out of heaven, not as the fathers ate and died; he who eats this bread shall live forever." (John 6:57,58)
This is "eating" Jesus by taking Jesus into each chamber of our hearts.
This is believing that Jesus can be enjoyed in every corner of our living.
This is taking in Jesus Christ where ever there is a hunger for life and right living.
This is allowing God to work Jesus Christ into all the total "fabric" of our human living by means of enjoying Jesus and feasting on Jesus. In short that is exercising our believing on and into Jesus.
