3:9-18 Here again is shown that all mankind are under the guilt of sin, as a burden; and under the government and dominion of sin, as enslaved to it, to work wickedness. This is made plain by several passages of Scripture from the Old Testament, which describe the corrupt and depraved state of all men, till grace restrain or change them. Great as our advantages are, these texts describe multitudes who call themselves Christians. Their principles and conduct prove that there is no fear of God before their eyes. And where no fear of God is, no good is to be looked for.There is none that understandeth,.... This is rightly concluded, from what the Psalmist says, Psalm 14:2, "The Lord looked down from heaven upon the children of men", on all the children of men, Jews and Gentiles, "to see if there were any that did understand"; and it appears, upon this survey of them, there was not one understanding person among them: man thinks himself a very wise and understanding creature, though he is born a very ignorant one: true indeed, he has not lost by sin the natural faculty of the understanding, so as to become like the horse and mule, which are without any; and it must be allowed, that natural men have some understanding of things natural, civil, and moral; though there is none that understands even these, as Adam did: but then they have no understanding of things spiritual; no spiritual knowledge of God; no true sense of themselves, their sin and misery; nor do they truly know the way of salvation by Christ; nor have they any experience of the work of the Spirit of God upon their souls; nor any experimental knowledge of the doctrines of the Gospel: no man can understand these of himself, by the mere strength of reason, and light of nature; nor can even a spiritual man fully understand them in this life; in consequence of this account and character of men it follows, that

there is none that seeketh after God; that worships him in Spirit and in truth, or prays to him with the Spirit, and with the understanding; who seek him chiefly, and in the first place, with their whole hearts, earnestly, diligently, and constantly; who seek him in Christ, and under the assistance of the Spirit; who seek after the knowledge of God in Christ, communion with him through the Mediator, or his honour and glory.
