Charles H. Spurgeon on Psalms 119:37

Quicken thou me. Every saint is very apt to be a sluggard in the way and work of God. "Quicken me, "says one of the chiefest and choicest of saints, "in thy way"; and it is as much as if he should say in plain terms, "Ah, Lord! I am a dull jade, and have often need of thy spur, thy Spirit." This prayer of David seems proof enough to this point; but if you desire farther confirmation, I shall produce an argument instar omnium, "that none shall dare to deny, nor be able to disapprove"; and that is drawn from the topic of your own experience; and this is argumentum lugubre, like a funeral anthem, "very sad and sorrowful." Do you not feel and find, to the grief of your own souls, that, whereas you should weep as if you wept not, rejoice as if you rejoiced not, and buy as if you possessed not; inverso ordine, "inverting this order, "you weep for losses as if you would weep out your eyes; you rejoice in temporal comforts as if you were in heaven; and you buy as if it were for ever and a day (Psalms 49:11). But e contrario, "on the contrary, "you pray as if you prayed not; hear as if you heard not; work for God as' if you worked not. Now, we know, experto credas, ("You may yield credence to that of which you have made trial.") a man that sticks fast in a ditch needs no reason to prove he is in, but remedies to pull him out. Your best course will be to propose the case how you may get rid of this unwelcome guest, spiritual sloth: it is a case we are all concerned in, Asini aures quis non habet ("where is the man who hath not the ears of an ass?") Every man and mortal hath some of the ass's dulness and sloth in him. Simmons, in "The Morning Exercises, "1661.
