Augustine of Hippo
Here is my strength, O Lord, and I shall place my trust solely in You; I will not rely on my own abilities. For what righteousness have I achieved that would warrant Your mercy and justification? What do You see in me except for my sins? All that is Yours is the creation of Your own hand; everything else consists of my wicked actions, which You have erased. It was not I who sought You first, but You have come to rouse me, for Your compassion is ever before me. Before I can accomplish any good, Your grace will precede me. What can I say to the distressed Pelagius?
