In this in-depth exploration of the fifty-first Psalm, Robert S. Candlish divides the psalm into four parts: the confession of sin, the supplication for full cleansing, its purpose of reparation, and its present sacrifice and final prospect.
“These are the two features in respect of which the ‘godly sorrow which worketh repentance to salvation not to be repented of’ differs from ‘the sorrow of the world which worketh death’ (2 Cor. 7:10); the desire to be thoroughly cleansed, and the owning of all sin. And they are the distinguishing features of this case; the case of one deeply, deplorably, fallen in sin; but yet hopeful.” (Pages 10–11)
“Then may I hope to behold the glory of the free grace and sovereign mercy of my God, emerging and shining forth out of the deep, dark cloud of righteous retribution.” (Page 26)
“Behold, I was shapen in iniquity; and in sin did my mother conceive me” (Page 14)
“What do I hear? See! I see one fairer than the sons of men, the Son of God himself, baring his bosom as he presents himself to the righteous Father, answering in the judgment for me! Hear! I hear that awful voice,—‘Awake, O sword, against my shepherd, against the man that is my fellow, saith the Lord!’ So righteous is the stroke impending over me,—so inexorably just the judicial retribution which I have deserved,—that even in richest and freest mercy, it cannot be averted, or turned away. It must descend and take effect. It must come down.” (Page 26)
“The first recognises the sovereignty of God. The second adores his holiness. The third acquiesces in his righteous judgment.” (Page 16)
