Charles H. Spurgeon on Psalms 17:14

"Men which are thy hand," etc. What shall we say then? Because God maketh use of thy sins, art thou excused? Is not thine evil evil, because he picketh good out of it? Deceive not thyself therein. When thou hast done such service to thy Master and Maker, though seven and seven years, as Jacob did service to Laban, thou shalt lose thy wages and thy thanks too. Oh, well were thou if thou didst but lose, for thou shalt also gain a sorrowful advantage. It is unprofitable, nay, miserable service which thou hast thus bestowed. Babylon shall be the hammer of the Lord a long time to bruise the nations, himself afterwards bruised; Asshur his rod to scourge his people, but Asshur shall be more scourged. These hammers, rods, axes, saws, other instruments, when they have done their offices, which they never meant, shall be thrown themselves into the fire, and burnt to ashes. Satan did service to God, it cannot be denied, in the afflicting of Job, winnowing of Peter, buffeting of Paul, executing of Judas, and God did a work in all these either to prove patience, or to confirm faith, or to try strength, or to commend justice; yet is Satan "reserved in chains under darkness, to the retribution of the great day." Judas did service to God, in getting honour to his blessed name for the redemption of mankind, whilst the worlds endureth, yet was his wages an alder-tree to hang himself upon, and, what is worse, he hangeth in hell for eternal generations. He had his wages, and lost his wages. That which the priest gave him, he lost, and lost his apostleship, but gained the recompense of everlasting unhappiness, and lies in the lowest lake, for the worm and death to gnaw upon without ceasing. —John King.
