QUOTATION: Serving God Must Be Unconditional

Many, on the other hand, are willing to serve God, but it must be in such an employment, in such a place, with such companions, or under such circumstances, or else they either quit the work, or do it with an ill-will. Such persons have not freedom of spirit, but are slaves of self-love; and on that account gain very little merit by what they do; they lead a troubled life, because the yoke of Jesus Christ becomes a burden to them.

--St. Alphonsus Liguori, The Holy Eucharist
