Quote by D.A. Carson

“(1) David’s initial appeal is to God’s faithfulness and righteousness (143:1). This is entirely appropriate, in exactly the same way that the goodness of a potentate or the integrity of a judge is welcomed by those trying to redress a wrong. The difficulty, of course, is that as we sinners appeal to the righteousness of God for vindication, it is easy to remember that we ourselves are horribly soiled compared with the clean glory of the unshielded holiness of the Almighty. Hence verse 2: David acknowledges that “no one living is righteous before you.” This is a tension not finally resolved until the cross (Rom. 3:21-26; cf. 1 John 1:9).”
