Charles H. Spurgeon on Psalms 119:107

According unto thy word. David goes often over with that phrase, which imports that David lay under the sense of some promise which God had made for the quickening of his heart when it was out of frame, and accordingly he recounts the gracious influences of God's Spirit, and professes that he will never forget his precepts, because by them he had quickened him: Psalms 119:93.

Thus, lay your dead hearts at Christ's feet, and plead in this manner: Lord, my heart is exceedingly dull and distracted; I feel not those enlarging, melting influences which thy saints have felt; but are they not chief material mercies of the covenant? dost thou not promise a spirit of illumination, conviction, and humiliation? is not holiness of heart and life a main branch of it? dost thou not promise therein to write thy law in my heart? to give me oneness of heart, to put thy fear within me, to subdue my corruptions, to help my infirmities in prayer? Now, Lord, these are the mercies my soul wants and waits for, fill my soul with these animating influences, revive thy work of grace in my soul, draw out my heart towards thee, increase my affection for thee, repair thine image, call forth grace into lively exercise. Doth not that gracious word intend such a mercy when thou sayest thou wilt not only give a new heart, but "put a new spirit within me" (Ezekiel 36:26), to make my soul lively, active, and spiritual in duties and exercises? Dear Lord, am not I in covenant with thee? and are not these covenant mercies? why, then, my God, is my heart thus hardened from thy fear? why dost thou leave me in all this deadness and distraction? Remember thy word unto thy servant in which thou hast caused me to hope, and which thou hast helped me to plead; O quicken my dull heart according to thy word. Oliver Heywood.
