Confessions of St. Augustine

Great art Thou, O Lord, and greatly to be praised; great is Thy power, and Thy wisdom infinite. And Thee would man praise; man, but a particle of Thy creation; man, that bears about him his mortality, the witness of his sin, the witness that Thou resistest the proud: yet would man praise Thee; he, but a particle of Thy creation. Thou awakest us to delight in Thy praise; for Thou madest us for Thyself, and our heart is restless, until it repose in Thee. Grant me, Lord, to know and understand which is first, to call on Thee or to praise Thee? and, again, to know Thee or to call on Thee? for who can call on Thee, not knowing Thee? for he that knoweth Thee not, may call on Thee as other than Thou art.
