Reference

15 And as the people were in expectation, and all men mused in their hearts of John, whether he were the Christ, or not; 16 John answered, saying unto them all, I indeed baptize you with water; but one mightier than I cometh, the latchet of whose shoes I am not worthy to unloose: he shall baptize you with the Holy Ghost and with fire: 17 Whose fan is in his hand, and he will throughly purge his floor, and will gather the wheat into his garner; but the chaff he will burn with fire unquenchable. (Luke 3:15-17 KJV)

William Burkitt’s Commentary

Observe here, 1. How the extraordinariness of John the Baptist’s person, the earnestness of his preaching, the acceptableness of his doctrine, and the exemplariness of his conversation, drew all persons to an admiration of him; insomuch that they began to think within themselves, whether here were not the Messiah himself. He plainly tells them he was not, but only his servant, his harbinger and forerunner.

Observe 2. The high opinion which John had of Christ, He is mightier than I; that is, a person of greater authority, dignity, and excellency, than myself.

From whence may be gathered, that though Christ was man, he was more than man, even very God, equal with the Father: for John himself was the greatest of them that were born of women. Mt 11:11 Yet, says John, Christ is mightier than I. How so? In regard of the dignity of his person, being both God and man? He that cometh after me is mightier than I.

Observe, 3. The humble and low estimation that the holy Baptist had of himself: His shoe-latchet I am not worthy to unloose: a proverbial speech, implying that he was unworthy to do the lowest offices, and meanest services for Christ.

Lord, how well does humility of mind, a humble apprehension, and a low opinion of themselves, become the messengers and ministers of Christ! John was a man of eminent abilities, yet of exemplary humility; he thought himself unworthy to unloose Christ’s shoe.

Observe, 4. John does not only declare the dignity of Christ’s person but the excellency of his office; He shall baptize you with the Holy Ghost and with fire. As if he had said, “I only wash the body with water, but Christ cleanses the soul by the operation of his Holy Spirit, which is as fire in the effects of it, purifying the hearts of his people from sin, and consuming their lusts and corruptions; yet at the same time having fiery indignation, and flaming judgments, to destroy and burn up impenitent sinners like dry stubble.”

Observable it is in scripture, that Christ is represented by one and the same metaphor of fire, in a way of comfort to his children, and in a way of terror to his enemies; he is fire unto both. He sits in the hearts of his people as a refiner’s fire; he is amongst his enemies as a consuming fire: a fire for his church to take comfort in, a fire for his enemies to perish by.

Observe, lastly, how the holy Baptist compares our Saviour to a husbandman, and the Jewish church to a barn floor; the office of a husbandman is to thresh, fan, and winnow, his corn, separating it from the chaff, preserving the one, and consuming the other.

Observe, 1. That the church is Christ’s floor.

2. That this floor Christ will purge, and that thoroughly.

3. That the word of Christ is the fan in his hand, by and with which he will thoroughly purge his floor.

The church is compared to a floor, upon the account of that mixture which is in the church. In a floor there is straw as well as grain, chaff as well as corn, tares as well as wheat, cockle, and darnel as well as good seed. Thus in the church there has been, there is, and ever will be, a mixture of good and bad, saints and sinners, hypocrites and sincere Christians: but this floor Christ will purge; purge it, but not break it up; purge out its corruptions, but not destroy its essence and existence: and the fan in Christ’s hand, with which he will purge his floor, is his holy word, accompanied with the wing of discipline. The fan detects and discovers the chaff, and the wing dissipates and scatters it; and by the help of both the floor is purged: His fan is in his hand, and he will thoroughly purge.
