And were baptized by him in the Jordan, confessing their sins.
All Commentaries on Matthew 3:6 Go To Matthew 3
John Chrysostom
AD 407
Having described the preaching of John, he goes on to say, “There went out to him,” for his severe life preached yet more loudly in the desert than the voice of his crying. Also the manner of his preaching being other than that of the old prophets had must effect; for now they heard not such things as they were wont to hear, such as wars, and conquests of the king of Babylon, or of Persia; but of Heaven and the Kingdom there, and the punishment of hell.
Compared with the holiness of John, who is there that can think himself righteous? As a white garment if placed near snow would seem foul by the contrast; so compared with John every man would seem impure; therefore they confessed their sins. Confession of sin is the testimony of a conscience fearing God. And perfect fear takes away all shame. But there is seen the shame of confession where there is no fear of the judgment to come. But as shame itself is a heavy punishment, God therefore bids us confess our sins that we may suffer this shame as punishment; for that itself is a part of the judgment.
