The Grace from my grandfather's prayer book (Men in prayer).
Before Meal
O God from whom we have everything
We praise you for your gifts.
You feed us because you love us
O bless also what you give us.
Amen.
After Meal
O God, praise and thanks be to you
For food and drink for all good things.
You have given and always want to give:
Our whole lives praise you.
Amen.
