Thomas a' Kempis
Those things that one cannot improve in himself or in others, he ought to endure patiently, until God arranges things otherwise. Nevertheless when you have such impediments, you ought to pray that God would help you, and that you may bear them kindly. Endeavor to be patient in bearing with the defects of others, whatever they are; for you also have many failings which must be borne by others. If you cannot make yourself be as you would like to be, how can you expect to have another person be to your liking in every way? We desire to have others perfect, and yet we do not correct our own faults. We would allow others to be severely corrected, and will not be corrected ourselves. We will have others kept under by strict laws, but in no case do we want to be restrained. And so it appears that we seldom weigh our neighbor in the same balance with ourselves.
