Imitation of Christ

Quæ rarissime homo in se vel in aliis emendare non valet, debet patienter sustinere, donec Deus aliter ordinet. Cogita quod sic forte melius est pro tua probatione et patientia, sine qua non sunt multum ponderanda merita nostra. Debes tamen pro talibus impedimentis supplicare, ut tibi dignetur Deus subvenire, ut possis benigne portare.

Those things which a man cannot amend in himself or in others, he ought patiently to bear, until God will otherwise ordain. Don't you think that perhaps it is better for your trial and patience, without which our merits are but little worth. Nevertheless you ought, when you find such impediments, to beseech God that He would sustain you, that you might be able to bear them with a good will.

Imitation of Christ, I, 16:1
