Patience is necessary in this life because so much of life is fraught with adversity. No matter how hard we try, our lives will never be without strife and grief. Thus, we should not strive for a peace that is without temptation, or for a life that never feels adversity. Peace is not found by escaping temptations, but by being tried by them. We will have discovered peace when we have been tried and come through the trial of temptation.
Thomas a KempisAnyone who is not totally dead to himself will soon find that he is tempted and overcome by piddling and frivolous things. Whoever is weak in spirit, given to the flesh and inclined to sensual things can, but only with great difficulty, drag himself away from his earthly desires. Therefore he is often gloomy and sad when he is trying to pull himself away from them, and easily gives way to anger should someone attempt to oppose him.
