Psalms 51:13 - Coke's Commentary on the Holy Bible

And sinners shall be converted unto thee— i.e. "Be persuaded, by my declaring to them the mercy I have experienced in the forgiveness of my sins, to return to thee by repentance, that they also may obtain the pardon of their offences." Happy for mankind, says Dr. Delaney, upon the consideration urged by David in this verse,—that there is such an instance, an authentic instance, of falling virtue and recovering guilt; an instance, so fitted to mortify the vanity of virtue, and the excellence of exalted piety; to raise the power and preciousness of humble penitence, to abate the pride of self-sufficiency, and support the hope of frailty! Who can confide in his own strength when he sees a David fall! Who can despair of divine mercy when he sees him forgiven! Sad triumph of sin over all that is great and excellent in man! Glorious triumph of repentance [and grace] over all that is shameful and dreadful in sin! Book iv. c. 24.
