Charles H. Spurgeon on Psalms 116:2

Therefore will I call upon him. If the hypocrite speed in prayer, and get what he asks, then also he throws up prayer, and will ask no more. If from a sick bed he be raised to health, he leaves prayer behind him, as it were, sick abed; he grows weak in calling upon God, when at his call God hath given him strength. And thus it is in other instances. When he hath got what he hath a mind to in prayer, he hath no more mind to pray. Whereas a godly man prays after he hath sped, as he did before, and though he fall not into those troubles again, and so is not occasioned to urge those petitions again which he did in trouble, yet he cannot live without prayer, because he cannot live out of communion with God. The creature is as the white of an egg, tasteless to him, unless he enjoy God. David saith, "I love the LORD, because he hath heard my voice and my supplications"; that is, because he hath granted me that which I supplicated to him for. But did this grant of what he had asked take him off from asking more? The next words show us what his resolution was upon that grant. "Because he hath inclined his ear unto me, therefore will I call upon him as long as I live";as if he had said, I will never give over praying, forasmuch as I have been heard in prayer. Joseph Caryl.
