you suffer always in vain for the life to come, and frequently even for this life.

Context

““What is most deplorable in your situation, Gentlemen, is, that in a life hard and painful, in which the services and the duties sometimes go beyond the rigour and severity of the most austere cloisters; you suffer always in vain for the life to come, and frequently even for this life. Alas! the solitary monk in his cell, obliged to mortify the flesh and to subject it to the spirit, is supported by the hope of an assured recompence, and by the secret unction of that grace which softens the yoke of the Lord.” source
