Charles H. Spurgeon on Psalms 17:6

"I have called upon thee, for thou wilt hear me, O God." Thou hast always heard me, O my Lord, and therefore I have the utmost confidence in again approaching thine altar. Experience is a blessed teacher. He who has tried the faithfulness of God in hours of need, has great boldness in laying his case before the throne. The well of Bethlehem, from which we drew such cooling draughts in years gone by, our souls long for still; nor will we leave it for the broken cisterns of earth. "Incline thine ear unto me, and hear my speech." Stoop out of heaven and put thine ear to my mouth; give me thine ear all to myself, as men do when they lean over to catch every word from their friend. The Psalmist here comes back to his first prayer, and thus sets us an example of pressing our suit again and again, until we have a full assurance that we have succeeded.
