Human wants are indeed insatiable and seem to be unending however our immediate needs are few. The basic needs of life are typical for all - food, shelter and clothing; any other need is secondary. The most important of these needs is food because it is required for sustenance. No reasonable and amount of work can be done without the nourishment supplied from the intake of food. Food is indeed essential for life.
One of the many phrases Jesus employed in describing himself is the Bread of Life. Since bread is a general term used for food in light of this phrase, it implies that Jesus is essential for life. The life being referred to here is not physical life but the life of God - eternal life. This life is for anyone who believes in Him as the Son of God. It is a life of triumph and abundance. One important way of contracting this life is by eating the flesh of Jesus, which is symbolic of the Lord’s Passover popularly known as Holy Communion. Observing this commandment implies that we are one with Him and share in His life. We enjoy all the benefits that are accrued to this meal and experience a real and fulfilling life.

Dear Heavenly Father, thank You for making me a partaker of the divine life in Christ by virtue of His death and resurrection. I am grateful for the grace to accept the call to a life of triumph and abundance. I bless You for the grace that guaranteed my salvation. Father Lord, let me not dissociate from You through unbelief. Help me trust and depend on You as my sufficiency and as my everything. Let me experience the benefits of eating Your flesh and let Your life be evident in mine.
In Jesus's name I pray. Amen.
