Godliness

I know of no part of the Holy Scriptures where the nature and evidence of true and sincere godliness are so fully and largely insisted on and delineated, as in the 119th Psalm. The Psalmist declares his design in the first verses of the psalm, keeps his eye on it all along, and pursues it to the end. The excellency of holiness is represented as the immediate object of a spiritual taste and delight. God's law, that grand expression and emanation of the holiness of God's nature, and prescription of holiness to the creature, is all along represented as the great object of the love, the complacence, and rejoicing of the gracious nature, which prizes God's commandments above gold, yea, the finest gold, and to which they are sweeter than honey, and the honeycomb; and that upon account of their holiness. 

Jonathan Edwards, quoted in Charles Spurgeon's The Treasury of David, on Psalm 119, verse 103.
