Charles H. Spurgeon on Psalms 119:40

Quicken me in thy righteousness. The petition is for liveliness in the knowledge and practice of holiness, according to the tenor of God's word and by its operation on the heart. If any prefer by "righteousness" to understand the faithfulness or justice of God, whereby he has bound himself to give grace to those who trust in him, there is no objection to such an interpretation. It is in fact implied in the others. Whoever can truly use the language of this verse is regenerate. Before renewing grace the law was a dead letter. It was more; it was a hated letter. The carnal mind is not subject to the law of God, neither indeed can be. A sinner desires no restraint from the divine precepts. William S. Plumer.

HINTS TO PREACHERS.
