This prayer is found in the beginning of Augustine’s Confessions:
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.
What art Thou then, my God? what, but the Lord God? For who is
Lord but the Lord? or who is God save our God? Most highest, most
good, most potent, most omnipotent; most merciful, yet most just;
most hidden, yet most present; most beautiful, yet most strong, stable,
yet incomprehensible; unchangeable, yet all-changing; never new, never
old; all-renewing, and bringing age upon the proud, and they know
it not; ever working, ever at rest; still gathering, yet nothing lacking; supporting, filling, and overspreading; creating, nourishing, and maturing; seeking, yet having all things. Thou lovest, without passion; art jealous, without anxiety; repentest, yet grievest not; art angry, yet serene; changest Thy works, Thy purpose unchanged; receivest again what Thou findest, yet didst never lose; never in need, yet rejoicing in gains; never covetous, yet exacting usury. Thou receivest over and above, that Thou mayest owe; and who hath aught that is not Thine?
Oh! that I might repose on Thee! Oh! that Thou wouldest enter
into my heart, and inebriate it, that I may forget my ills, and embrace
Thee, my sole good!
Narrow is the mansion of my soul; enlarge Thou it, that Thou
mayest enter in. It is ruinous; repair Thou it. It has that within
which must offend Thine eyes; I confess and know it. But who shall
cleanse it? or to whom should I cry, save Thee? Lord, cleanse me from
my secret faults, and spare Thy servant from the power of the enemy.
