Charles H. Spurgeon on Psalms 18:23

"I kept myself." Keep himself! Who made man his own keeper! It's the Lord that is his keeper: he is the keeper of Israel, and the preserver of man. If a man cannot keep himself from sorrow, how is he able to keep himself from sin? God indeed in our first conversion works upon us as he did upon the earth, or Adam's body in paradise, before he breathed a soul into it, and made it a living creature; such a power as Christ put forth on Lazarus in his grave, for we are "dead in trespasses and sins;" but yet being living he must walk and act of himself, the Lord will have us to co-operate together with him, for we are built upon Christ, not as dead, but as "living stones." 1 Peter 2:5. The grace whereby we are made alive is his, and the power is his; and yet by his grace we do it also; ille facit ut nos faciamus, quae praecepit (Augustine). —William Strong.
