From the additional notes to Charles Spurgeon's The Treasury of David, on Psalm 119, verse 25.
Quicken thou me. To whom shall the godly fly when life faileth but to that Wellspring of all life? Even as to remove cold the next way is to draw near the fire, so to dispel any death, the next way is to look to him who is our root, by whom we live this natural life. All preservatives and restoratives are nothing, all colleges of physicians are vanity, if compared with him. Other things which have not life, give life as the instruments of him who is life, as fire burneth being the instrument of heat. "When heart and flesh fail, God is the strength of my heart." As a man can let a fire almost go out which had been kindled, and then blow it up, and by application of new fuel make it blaze as much as ever: so can God deal with this flame of life which he hath kindled. Paul Bayne.
