There was a reason why the tradition to say grace before eating came about. A practical way to acknowledge God and to give thanks - otherwise one may sink into the sensuality of eating with the latent fear of dying without food!
Ever watch a documentary on the wonders of nature, the beauty and amazing variety. Nowadays, instead of giving God the glory, there is an undertone of fear that we may lose it all due to man's invasive mode of operation! - the ever-present fear that accompanies a Godless view of the universe.
The arrogance of man before the Omnipotent, Omnipresent, Omniscient! If the epidemics of depression, anxiety, obesity, addiction, etc. are any indication, for all his advancements, mankind has no reason at all to glory in himself.
"Mortals are egotists. They believe themselves to be independent workers, personal authors, and even privi leged originators of something which Deity would not or could not create. The creations of mortal mind are material. Immortal spiritual man alone represents the truth of creation." (S&H)
From this vantage point, man is empowered by his Maker to humbly deal with the challenges around him, by aligning himself with his divine Principle, Love. "As in Adam all die, even so in Christ shall all be made alive." (I Cor. 15)
