Recommended Book: First Epistle of Clement to the Corinthians - Kindle Edition (get Kindle app for phone) (paid link)

God,
you are like a mother to us all,
nourishing all creatures with food and with blessing.
Strengthen my child with (my milk, this food)
and with the warmth of our nearness.

Or:

Blessed are you, Lord, God of all creation:
you nourish all your children.
