Praying before we eat a meal is a beautiful thing — or should be a beautiful thing. It is gloriously appropriate to give thanks and praise to God from whom all blessings flow. And to have food to eat is a merciful blessing.
The Dark Side of Abundance
Those of us who live in prosperous regions of the globe and have never known food scarcity perhaps don't feel much awe in it. That is a sad thing: a lack of awe. It's the dark side of abundance. We sinners tend to grow blind to glory when there's a lot of it. God is kind not to give us heaven yet. We would not appreciate more than a fraction of it.
Assuming there will always be way more food available than we need is a luxury very few have experienced in world history. Complaining about the food we have is a luxury hundreds of millions don’t experience now. If we lack gratitude, repentance is the only appropriate response.
Every Meal Is a Miracle
It should shock us that we don't bow down in worship every time we come to a table full of food. God's design in our experience of eating is simply marvelous.
Receiving strength by eating food is itself an astonishing concept. But God made eating more than pragmatic; through smell, taste, and texture he made it enjoyable for us! And he made it even more enjoyable when we share the experience with others — wherever two or more are gathered, there (typically) food is in their midst. He also made the preparation of food to be an art as well as an act of servant-hearted love. Strength. Joy. Community. Service.
And time would fail me to talk of all the vocations and human ingenuity involved in growing, nurturing, packaging, distributing, selling, and buying food.
Every meal is a miracle.
