Then with many other exhortations he preached good news to the people,
      (2.) He owns him to have a greater energy than he had: "He is mightier than I, and does that which I cannot do, both for the comfort of the faithful and for the terror of hypocrites and dissemblers." They thought that a wonderful power went along with John; but what was that compared with the power which Jesus would come clothed with? [1.] John can do no more than baptize with water, in token of this, that they ought to purify and cleanse themselves; but Christ can, and will, baptize with the Holy Ghost; he can give the Spirit to cleanse and purify the heart, not only as water washes off the dirt on the outside, but as fire purges out the dross that is within, and melts down the metal, that it may be cast into a new mould. [2.] John can only preach a distinguishing doctrine, and by word and sign separate between the precious and the vile; but Christ hath his fan in his hand, with which he can, and will, perfectly separate between the wheat and the chaff. He will thoroughly purge his floor; it is his own, and therefore he will purge it, and will cast out of his church the unbelieving impenitent Jews, and confirm in his church all that faithfully follow him. [3.] John can only speak comfort to those that receive the gospel, and, like other prophets, say to the righteous that it shall be well with them; but Jesus Christ will give them comfort. John can only promise them that they shall be safe; but Christ will make them so: he will gather the wheat into his garner; good, serious, solid people he will gather now into his church on earth, which shall be made up of such, and he will shortly gather them into his church in heaven, where they shall be for ever sheltered. [4.] John can only threaten hypocrites, and tell the barren trees that they shall be hewn down and cast into the fire; but Christ can execute that threatening; those that are as chaff, light, and vain, and worthless, he will burn with fire unquenchable. John refers here to Malachi 3:18; Malachi 4:1; Malachi 4:2. Then, when the floor is purged, ye shall return, and discern between the righteous and the wicked, for the day comes that shall burn as an oven.
