Charles H. Spurgeon on Psalms 119:49

Remember the word unto thy servant, etc. God promises salvation before he giveth it, to excite our desire of it, to exercise our faith, to prove our sincerity, to perfect our patience. For these purposes he seemeth sometimes to have forgotten his word, and to have deserted those whom he had engaged to succour and relieve; in which case he would have us, as it were, to remind him of his promise, and solicit his performance of it. The Psalmist here instructs us to prefer our petition upon these grounds; first, that God cannot prove false to his own word: "Remember thy word; "secondly, that he will never disappoint an expectation which himself hath raised: "upon which thou hast caused me to hope." George Horne.

Ver. 49,52,55. Remember. "I remembered." As David beseeches the Lord to remember his promise, so he protests, in Psalms 119:52, that he remembered the judgments of God, and was comforted; and in Psalms 119:55, that he remembered the name of the Lord in the night. It is but a mockery of God, to desire him to remember his promise made to us, when we make no conscience of the promise we have made to him. But alas, how often we fail in this duty, and by our own default, diminish that comfort we might have of God's promises in the day of our trouble. William Cowper.
