Here is a sample prayer before meals that you can use as a guide:
Dear God,
We thank you for this food and for the many blessings you have given us. Please bless this meal and those who have prepared it.
We ask that you would provide for those who are hungry and in need. Please bring them your comfort and hope.
We pray for your guidance and direction in our lives. Please be with us and help us to serve you to the best of our ability.
In your holy name we pray, Amen.
