John 4 31- 34
Meanwhile the disciples besought him, saying, “Rabbi, eat” but he said to them, “I have food to eat of which you do not know”. So the disciples said to one another, “has anyone brought him food?” Jesus said to them, “my food is to do the will of Him who sent me and to accomplish his work”
When the disciples asked Jesus to eat he denied, it was not that he had eaten earlier but wanted to show his disciples who the true food was and not the worldly food which passes with time.
Jesus himself initiated the sacrament, which followers cerebrate to commemorate the death and resurrection of him, this is a symbol of everlasting food of the soul.
Do you realize that we should depend on God for his spiritual food daily as Jesus did?
