Tertullian

“ Where the injury is less, there is no necessity for impatience; but where the injury is greater, there more necessary is the remedy for the injury—patience. Let us strive, therefore, to endure the inflictions of the Evil One, that the counter-zeal of our equanimity may mock the zeal of the foe. If, however, we ourselves, either by imprudence or else voluntarily, draw upon ourselves anything, let us meet with equal patience what we have to blame ourselves for. Moreover, if we believe that some inflictions are sent on us by the Lord, to whom should we more exhibit patience than to the Lord? ”

“ On every side, therefore, we are bound to the duty of exercising patience, from whatever quarter, either by our own errors or else by the snares of the Evil One, we incur the Lord’s reproofs. Of that duty great is the reward—namely, happiness. For whom but the patient has the Lord called happy, in saying, “Blessed are the poor in spirit, for theirs is the kingdom of the heavens?” [3] No one, assuredly, is “poor in spirit,” except he be humble. Well, who is humble, except he be patient? For no one can abase himself without patience, in the first instance, to bear the act of abasement. ”
