The Soul of the Apostolate, page 20.
Dom J.-B. Chautard
If God calls me to apply my activity not only to my own sanctification, but also to good works, I must establish this firm conviction, before everything else, in my mind: Jesus has got to be, and wishes to be, the life of these works. My efforts, by themselves, are nothing, absolutely nothing...They will only be useful, and blessed by God, if by means of a genuine interior life I unite them constantly to the lifegiving action of Jesus. But then they will become all-powerful.
