Isaiah 45:9-10

How beautiful and striking is this figure of the potsherd, to shed the folly and danger of finding fault with God. Earthen vessels, struck one against another, will break; contentions among men are foolish; but contention against God, in any of his dispensations, of nature, providence, or grace, is madness itself. Equally senseless would be the expostulating of a child to its parent, concerning its being. What can a sinful father beget, but a sinful child; or a polluted mother bring forth, but pollution also? Who can bring a clean thing out of an unclean? Precious Jesus! how blessed dost thou appear in every view, when, in the consciousness of our corrupt state, we feel the need of that fountain which the soldier's spear opened in thy side, for sin and for uncleanness! Zechariah 13:1.
