Chapter 7. He Gives Thanks to God for the Remission of His Sins, and Reminds Every One that the Supreme God May Have Preserved Us from Greater Sins.
15. What shall I render unto the Lord, that while my memory recalls these things my soul is not appalled at them? I will love You, O Lord, and thank You, and confess unto Your name, Revelation 3:5 because You have put away from me these so wicked and nefarious acts of mine. To Your grace I attribute it, and to Your mercy, that You have melted away my sin as it were ice. To Your grace also I attribute whatsoever of evil I have not committed; for what might I not have committed, loving as I did the sin for the sin's sake? Yea, all I confess to have been pardoned me, both those which I committed by my own perverseness, and those which, by Your guidance, I committed not. Where is he who, reflecting upon his own infirmity, dares to ascribe his chastity and innocency to his own strength, so that he should love You the less, as if he had been in less need of Your mercy, whereby You forgive the transgressions of those that turn to You? For whosoever, called by You, obeyed Your voice, and shunned those things which he reads me recalling and confessing of myself, let him not despise me, who, being sick, was healed by that same Physician Luke 4:23 by whose aid it was that he was not sick, or rather was less sick. And for this let him love You as much, yea, all the more, since by whom he sees me to have been restored from so great a feebleness of sin, by Him he sees himself from a like feebleness to have been preserved.
