Charles H. Spurgeon on Psalms 119:171

My lips shall utter praise. You have stood at the fountain head of a stream of water, and admired while it bubbled up, and ran down in a clear little rivulet, till at length it swelled the mighty river. Such is the allusion here. The heart taught of God, cannot contain itself, but breaks out in praise and singing. This would be the effect of divine illumination, and this would be felt to be a privilege, yea, and a high duty. Have you not found so, believers, specially on common occasions? Be assured, such utterances are the sign of a renewed heart; yea, of a heart filled with all gratitude of right feeling. John Stephen.
