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.

12. Whose fan—winnowing fan.

is in his hand—ready for use. This is no other than the preaching of the Gospel, even now beginning, the effect of which would be to separate the solid from the spiritually worthless, as wheat, by the winnowing fan, from the chaff. (Compare the similar representation in Mal 3:1-3).

and he will throughly purge his floor—threshing-floor; that is, the visible Church.

and gather his wheat—His true-hearted saints; so called for their solid worth (compare Am 9:9; Lu 22:31).

into the garner—"the kingdom of their Father," as this "garner" or "barn" is beautifully explained by our Lord in the parable of the wheat and the tares (Mt 13:30, 43).

but he will burn up the chaff—empty, worthless professors of religion, void of all solid religious principle and character (see Ps 1:4).

with unquenchable fire—Singular is the strength of this apparent contradiction of figures:—to be burnt up, but with a fire that is unquenchable; the one expressing the utter destruction of all that constitutes one's true life, the other the continued consciousness of existence in that awful condition.

Luke adds the following important particulars (Lu 3:18-20):

Lu 3:18:

And many other things in his exhortation preached he unto the people—showing that we have here but an abstract of his teaching. Besides what we read in Joh 1:29, 33, 34; 3:27-36, the incidental allusion to his having taught his disciples to pray (Lu 11:1)—of which not a word is said elsewhere—shows how varied his teaching was.

Lu 3:19:

But Herod the tetrarch, being reproved by him for Herodias his brother Philip's wife, and for all the evils which Herod had done—In this last clause we have an important fact, here only mentioned, showing how thoroughgoing was the fidelity of the Baptist to his royal hearer, and how strong must have been the workings of conscience in that slave of passion when, notwithstanding such plainness, he "did many things, and heard John gladly" (Mr 6:20).

Lu 3:20:

Added yet this above all, that he shut up John in prison—This imprisonment of John, however, did not take place for some time after this; and it is here recorded merely because the Evangelist did not intend to recur to his history till he had occasion to relate the message which he sent to Christ from his prison at Machærus (Lu 7:18, &c.).
