Lord, teach me to be generous,
to serve you as you deserve,
to give and not to count the cost,
to fight and not to heed the wounds,
to toil and not to seek for rest,
to labor and not to look for any reward,
save that of knowing that I do your holy will.

(Attributed to Ignatius of Loyola,
but likely appeared much later,
perhaps inspired by his life and work)

The following prayer, however, was used by Ignatius in his Spiritual Exercises:

Take, Lord, and receive all my liberty,
my memory, my understanding,
and my entire will,
All I have and call my own.

You have given all to me.
To you, Lord, I return it.

Everything is yours; do with it what you will.
Give me only your love and your grace,
that is enough for me.
