You must have heard sermons on Psalm 19 that run something like this: General revelation is good but not enough (v.1-6), so God gives us the special revelation of the law (vv.7-11).
But that is not the end of the story. Verses 12-14 are a prayer for more:
- A further word of justification "declare me..."
- A further work of sanctification "keep back your servant"
It seems we need more than greater clarity, we need a different kind of revelation.
