A good prayer before eating is "Lord God, forgive us our trespasses. Thank you for the provision of this food, bless and sanctify it, bless the hands that prepared it, and replenish the source from which it came, in Jesus name, amen." The pre-meal prayer is also known as "Grace."
A good prayer before eating is a prayer that is straight to the point, and at the same time addresses the basic components of a good prayer. A good prayer is comprised of worship, confession, thanksgiving and supplication.
When praying before a meal, a person should offer words of worship to God and acknowledge His greatness. “Lord God” gives God the position of the boss in your life and places Him above everything, which serves as an act of worship. “Forgive us our trespasses” is an act of confession. Since the prayer is directly before a meal, there is no need to name sins one after another.
Over a meal, supplication should be as brief as possible, with a simple requet for a food blessing. If further prayer is desired, a good idea is to ask God to replenish the source from which the food came. Longer prayers are typically not a good idea before a meal, as people are hungry and waiting to eat.
