John Webster, on Psalm 119:1-16:

The point of all this is to try to say that God’s law is not just a graceless source of boligation. It’s a good gift, something which leads to joy, blessing, and praise. Properly speaking, law is about the fact that God comes to his people with his own kind of merciful majesty, showing us what we must be if we ar eto be truly human, setting the law between us and our limitless capacity for self-destruction. God’s law is God interposing himself between us adn our headlong rush into self-destruction, God nurturing us by educating us into the true form of human flourishing. If we would be, and if we would flourish, this is what it means to live joyfully from, with, and under God.

Christ Our Salvation, 21
