Charles H. Spurgeon on Psalms 18:26

"With the pure thou wilt shew thyself pure," etc. But doth the Lord take colour from every one he meets, or change his temper as the company changes? That's the weakness of sinful man: he cannot do so with whom there is no variableness nor shadow of changing. God is pure and upright with the unclean and hypocritical, as well as with the pure and upright, and his actions show him to be so. God shows himself froward with the froward when he deals with him as he hath said he will deal with the froward —deny them and reject them. God shows himself pure with the pure, when he deals with them as he hath said he will —hear them and accept them. Though there be nothing in purity and sincerity which deserveth mercy, yet we cannot expect mercy without them. Our comforts are not grounded upon our graces, but our comforts are the fruits or consequences of our graces. —Joseph Caryl.
