The following are the signs which indicate whether we work solely for God in any spiritual undertaking:
1. If we are not disturbed at the failure of our plans, because when we see it is not God s will, neither is it any longer our will.
2. If we rejoice at the good done by others, as heartily as if we ourselves had done it.
3. If we have no preference for one charge more than for another, but willingly accept that which obedience to Superiors enjoins us.
4. If after our actions we do not seek the thanks or approbation of others, nor are in any way affected if we be found fault with or scolded, being satisfied with having pleased God. And if when the world applauds us we are not puffed up, but meet the vain glory, which might make, itself felt, with the reply of the venerable John of Avila " Get away, thou comest too late, for all has been already given to God."
--St. Alphonsus Liguori, The Holy Eucharist
