"The Word is too sublime to pass under our judgment; it is the province of the Word to judge us. The world, however, while unwilling to be judged and convicted by us, essays to judge and convict the Word of God. Here God steps in. It would be a pity for the worldly to see a godly Christian, so God blinds them and they miss His kingdom. As Isaiah says (26:10): 'In the land of uprightness will he deal wrongfully, and will not behold the majesty of Jehovah.' For this reason, few real Christians come under the observation of cavilers*; the latter, in general, observe fools and fanatics, at whom they maliciously stumble and take offense. They are unworthy to behold God's honor in a godly Christian upon whom the Lord has poured out Himself in fulness of blessing."
