A PRAYER FOR ANIMALS
By: Albert Schweitzer
Hear our humble prayer, O God, for our friends the animals, especially for animals who are suffering; for any that are hunted or lost or deserted or frightened or hungry; for all that will be put to death.
We entreat for them all Thy mercy and pity, and for those who deal with them we ask a heart of compassion and gentle hands and kindly words.
Make us, ourselves, to be true friends to animals and so to share the blessings of the merciful.
