Charles H. Spurgeon on Psalms 119:17

Thy servant. That he styles himself so frequently the servant of God notes the reverent estimation he had of his God, in that he accounts it more honourable to be called the servant of God who was above him than the king of a mighty, ancient, and most famous people that were under him. And indeed, since the angels are styled his ministers, shall men think it a shame to serve him? and especially since he of his goodness hath made them our servants, "ministering spirits" to us? Should we not joyfully serve him who hath made all his creatures to serve us, and exempted us from the service of all other, and hath only bound us to serve himself? William Cowper.
