To give without counting the cost (St. Ignatius of Loyola)

 O my God, teach me to be generous, 

teach me to serve you as I should, 

to give without counting the cost, 

to fight without fear of being wounded, 

to work without seeking rest, 

to labour without expecting any reward 

but the knowledge that I am doing your most holy will.  

--St. Ignatius of Loyola
