Sinclair Ferguson on Righteousness and Meritoriousness

I was listening to this old talk by Sinclair Ferguson, speaking about the attributes of God. By bouncing off of Deuteronomy 24:13, he makes some thoughtful and helpful comments on how we should think about the idea of "righteousness" as used in the Scriptures...

So we need to dissolve from our understanding of righteousness any notion of meritoriousness that may have crept into our thinking. Righteousness means integrity of relationship to the covenant requirements. And consequently righteous acts in Scripture are thus nuanced. Again, in terms of human righteousness, when the saints in the Old Testament appeal to their own righteousness, they are appealing not to some Old Testament principle of meritoriousness, but to the integrity of relationship in which they stand to God, in terms of the covenant with them he has made. And consequently, righteousness set within this covenant context, manifests itself, in a multifaceted way, and with a series of nuances. Thus for example, Geerhardus Vos, suggests there are at least five different categories employable to expound the nuances of righteousness. Barton Payne in his Theology of the Older Testament suggests that there are nine. But we who like to be simple believers will suggest that we can focus our attention on two of those aspects which point up the vital characteristic of divine righteousness, namely the principle that in Scripture the righteousness of God is manifested both in terrible condemnation and in merciful deliverance. And this is so because of the absolute integrity of God to the revelation he has given of himself in his covenant. And if we lack that perspective, we are bound to minimize in one direction or another, what the concept of divine righteousness means, either limiting it to retributive justice or to love and grace.
