Matthew 3:9

“And think not to say within yourselves, etc.] John knew the sentiments of their minds, and the prevailing opinion they had given into, against which he cautions them; as, that because they were Abraham’s seed, they were in a state of salvation, in the favour of God, and had a right to all privileges and ordinances: this they trusted in, and boasted of, and would often think of it within themselves, pleasing themselves with the thoughts of it, and speak of it to others; we have Abraham for our father. The Baptist was aware how ready they would be to object this to him; and therefore prevents their plea from hence in favour of their admission to baptism, by assuring them, that this would have…”

“And think not to say within yourselves, We have Abraham to our father--that pillow on which the nation so fatally reposed, that rock on which at length it split. for I say unto you, that God is able of these stones to raise up children unto Abraham--that is, "Flatter not yourselves with the fond delusion that God stands in need of you, to make good His promise of a seed to Abraham; for I tell you that, though you were all to perish, God is as able to raise up a seed to Abraham out of those stones as He was to take Abraham himself out of the rock whence he was hewn, out of the hole of the pit whence he was digged" (Isa 51:1). Though the stem speaker may have pointed as he spoke to the pebbles…”

“And think not to say ... - They regarded it as sufficient righteousness that they were descended from so holy a man as Abraham. Compare John 8:33-37, John 8:53. John assured them that this was a matter of small consequence in the sight of God. Of the very stones of the Jordan he could raise up children to Abraham. The meaning seems to be this: God, from these stones, could more easily raise up those who should be worthy children of Abraham, or be like him, than simply, because you are descendants of Abraham, make you, who are proud and hypocritical, subjects of the Messiah’s kingdom. Or, in other words, mere nativity, or the privileges of birth, avail nothing where there is not righteousness…”

“And say not confidently - The word in the original, vulgarly rendered, Think not, seems here, and in many places, not to diminish, but rather add to the force of the word with which it is joined. We have Abraham to our father - It is almost incredible, how great the presumption of the Jews was on this their relation to Abraham. One of their famous sayings was, "Abraham sits near the gates of hell, and suffers no Israelite to go down into it." I say unto you - This preface always denotes the importance of what follows. Of these stones - Probably pointing to those which lay before them. Matthew 3:10”

“3:9 We’re safe: Some had wrongly assumed that, since they were descendants of Abraham, they were exempt from judgment. • A prominent theme in Matthew is how God will create new children of Abraham by bringing the Gentiles into God’s people and removing from his people Jews who reject the Messiah (see 8:11-12; 21:43; 22:1-14; 28:16-20; Rom 4:9-25; Gal 3:6-14, 29).”
