Work then, not for perishable food, but for the lasting food which gives eternal. John 6:27
Man strives for his food, and his first pre-occupations is to assure himself for the future, because if he does not eat, he will cease to live. Man does not have life in himself and has to constantly take from another what is necessary to maintain his life. But in spite of everything, some day, life escapes him, because he has not encountered the lasting food.
In fact, man needs much more than bread : Beyond eating and drinking, he needs spiritual and lasting food. He longs for something that permits him no longer to seek or to experience hunger or thirst. This is the food that the son of Man gives, for the Father’s seal has been put on him.
Jesus becomes our bread when we believe in him. He is the true bread from heaven. The bread that comes down from heaven, is not something, but someone, and that is Christ. This true bread communicates eternal life to us.
In the past, when the Israelites wandered in the desert and lacked everything, God gave them a provisional meal, the manna. Even though the Israelites had been receiving manna for forty years rebelled against God and died in the wilderness. Material things, although they may come from heaven, do not make us better nor do they give us true and ever lasting life.
For this reason, work then, not for perishable food, but for the lasting food which gives eternal life, the food that the Son of Man gives to you.
The gift of God is eternal life through Jesus Christ our Lord.
