3:7-12 To make application to the souls of the hearers, is the life of preaching; so it was of John's preaching. The Pharisees laid their chief stress on outward observances, neglecting the weightier matters of the moral law, and the spiritual meaning of their legal ceremonies. Others of them were detestable hypocrites, making their pretences to holiness a cloak for iniquity. The Sadducees ran into the opposite extreme, denying the existence of spirits, and a future state. They were the scornful infidels of that time and country. There is a wrath to come. It is the great concern of every one to flee from that wrath. God, who delights not in our ruin, has warned us; he warns by the written word, by ministers, by conscience. And those are not worthy of the name of penitents, or their privileges, who say they are sorry for their sins, yet persist in them. It becomes penitents to be humble and low in their own eyes, to be thankful for the least mercy, patient under the greatest affliction, to be watchful against all appearances of sin, to abound in every duty, and to be charitable in judging others. Here is a word of caution, not to trust in outward privileges. There is a great deal which carnal hearts are apt to say within themselves, to put aside the convincing, commanding power of the word of God. Multitudes, by resting in the honours and mere advantages of their being members of an outward church, come short of heaven. Here is a word of terror to the careless and secure. Our corrupt hearts cannot be made to produce good fruit, unless the regenerating Spirit of Christ graft the good word of God upon them. And every tree, however high in gifts and honours, however green in outward professions and performances, if it bring not forth good fruit, the fruits meet for repentance, is hewn down and cast into the fire of God's wrath, the fittest place for barren trees: what else are they good for? If not fit for fruit, they are fit for fuel. John shows the design and intention of Christ's appearing, which they were now speedily to expect. No outward forms can make us clean. No ordinances, by whomsoever administered, or after whatever mode, can supply the want of the baptism of the Holy Ghost and of fire. The purifying and cleansing power of the Holy Spirit alone can produce that purity of heart, and those holy affections, which accompany salvation. It is Christ who baptizes with the Holy Ghost. This he did in the extraordinary gifts of the Spirit sent upon the apostles, Ac 2:4. This he does in the graces and comforts of the Spirit, given to those that ask him, Lu 11:13; Joh 7:38,39; see Ac 11:16. Observe here, the outward church is Christ's floor, Isa 21:10. True believers are as wheat, substantial, useful, and valuable; hypocrites are as chaff, light and empty, useless and worthless, carried about with every wind; these are mixed, good and bad, in the same outward communion. There is a day coming when the wheat and chaff shall be separated. The last judgment will be the distinguishing day, when saints and sinners shall be parted for ever. In heaven the saints are brought together, and no longer scattered; they are safe, and no longer exposed; separated from corrupt neighbours without, and corrupt affections within, and there is no chaff among them. Hell is the unquenchable fire, which will certainly be the portion and punishment of hypocrites and unbelievers. Here life and death, good and evil, are set before us: according as we now are in the field, we shall be then in the floor.

11. I indeed baptize you with water unto repentance—(See on [1216]Mt 3:6);

but he that cometh after me is mightier than I—In Mark and Luke this is more emphatic—"But there cometh the Mightier than I" (Mr 1:7; Lu 3:16).

whose shoes—sandals.

I am not worthy to bear—The sandals were tied and untied, and borne about by the meanest servants.

he shall baptize you—the emphatic "He": "He it is," to the exclusion of all others, "that shall baptize you."

with the Holy Ghost—"So far from entertaining such a thought as laying claim to the honors of Messiahship, the meanest services I can render to that 'Mightier than I that is coming after me' are too high an honor for me; I am but the servant, but the Master is coming; I administer but the outward symbol of purification; His it is, as His sole prerogative, to dispense the inward reality." Beautiful spirit, distinguishing this servant of Christ throughout!

and with fire—To take this as a distinct baptism from that of the Spirit—a baptism of the impenitent with hell-fire—is exceedingly unnatural. Yet this was the view of Origen among the Fathers; and among moderns, of Neander, Meyer, De Wette, and Lange. Nor is it much better to refer it to the fire of the great day, by which the earth and the works that are therein shall be burned up. Clearly, as we think, it is but the fiery character of the Spirit's operations upon the soul—searching, consuming, refining, sublimating—as nearly all good interpreters understand the words. And thus, in two successive clauses, the two most familiar emblems—water and fire—are employed to set forth the same purifying operations of the Holy Ghost upon the soul.
