Our weakness and God's help
Blessed is the person who knows his own weakness, because awareness of this becomes for him the foundation and beginning of all that is good and beautiful. For whenever someone realizes and perceives that he is truly and indeed weak, then he draws in his soul from the diffuseness which dissipates knowledge, and he becomes all the more watchful of his soul.
But no one can perceive his own weakness unless he has been remiss a little, has neglected some small thing, has been surrounded by trials, either in the matter of things which cause the body suffering, or in that of ways in which the soul is subject to the passions. Only then, by comparing his own weakness, will he realize how great is the assistance which comes from God.
When someone is aware that he is in need of divine help, he makes many prayers. And once he has made much supplication, his heart is humbled, for there is no one who is in need and asks who is not humbled. "A broken and humbled heart, God will not despise." As long as the heart is not humbled it cannot cease from wandering; for humility concentrates the heart.
St. Issac of Syria
