Charles H. Spurgeon on Psalms 17:15

"When I awake," etc. The sincere Christian is progressive, never at his journey's end till he gets to heaven; this keeps him always in motion, advancing in his desires and endeavours forward: he is thankful for little grace, but not content with great measures of grace. "When I awake," saith David, "I shall be satisfied with thy likeness." He had many a sweet entertainment at the house of God in his ordinances. The Spirit of God was the messenger that brought him many a covered dish from God's table, inward consolations which the world knew not of. Yet David has not enough, it is heaven alone that can give him his full draught. They say the Gauls, when they first tasted of the wines of Italy, were so taken with their lusciousness and sweetness, that they could not be content to trade thither for this wine, but resolved they would conquer the land where they grew. Thus the sincere soul thinks it not enough to receive a little now and then of grace and comfort from heaven, by trading and holding commerce at a distance with God in his ordinances here below, but projects and meditates of that holy land and blessed place from which such rich commodities come, that he may drink the wine of that kingdom in that kingdom. —William Gurnall.
