“In those days,” i.e. at the time of Jesus Christ, whose history this book contains. This expression does not always mean that what is going to be narrated, happened immediately after that which precedes. (Bible de Vence) — ‘Tis a way of speaking used by the Hebrews, even when there is no connection of time, as here are passed over 30 years of Christ’s life. John the Baptist was so called from his baptizing the people in water. The Jews took this for some token of their Messias: for they said to him, (John i. 25,) why dost thou baptize if thou art not the Christ? — In the desert, not in the house of his Father Zacharias, as some pretend, but in a true wilderness, as appears by the circumstances of his food, apparel, &c. (Witham) — The Baptist was about 30 years of age. He, as well as our Lord, in conformity with the Jewish law, did not enter upon his public ministry before that age. (Haydock)
In a hilly country, which was notwithstanding inhabited, for Zechariah dwelt there, Luke 1:40 , and there was Joab’s house, 1 Kings 2:34 ; and besides these, Joshua maketh mention of six towns that were in the wilderness, Josh. 15:62 . Cross references: : Mark 1:4 ; Luke 3:3 John, who through his singular holiness and rare austereness of life caused all men to cast their eyes upon him, prepareth the way for Christ following fast on his heels, as the Prophet Isaiah foretold, and delivereth the sum of the Gospel, which in short space after should be delivered more fully. Not when Joseph went to dwell at Nazareth, but a great while after, about the space of 15 years: for in the 30 year of his age was Jesus baptized of John: therefore by those days is meant, at that time that Jesus remained as yet an inhabitant of the town of Nazareth.
III. His preaching. This he made his business. He came, not fighting, nor disputing, but preaching (v. 1); for by the foolishness of preaching, Christ's kingdom must be set up.
Verses 1-6 After Malachi there was no prophet until John the Baptist came. He appeared first in the wilderness of Judea. This was not an uninhabited desert, but a part of the country not thickly peopled, nor much enclosed. No place is so remote as to shut us out from the visits of Divine grace. The doctrine he preached was repentance; "Repent ye." The word here used, implies a total alteration in the mind, a change in the judgment, disposition, and affections, another and a better bias of the soul. Consider your ways, change your minds: you have thought amiss; think again, and think aright. True penitents have other thoughts of God and Christ, sin and holiness, of this world and the other, than they had. The change of the mind produces a change of the way. That is gospel repentance, which flows from a sight of Christ, from a sense of his love, and from hopes of pardon and forgiveness through him. It is a great encouragement to us to repent; repent, for your sins shall be pardoned upon your repentance. Return to God in a way of duty, and he will, through Christ, return unto you in the way of mercy. It is still as necessary to repent and humble ourselves, to prepare the way of the Lord, as it then was. There is a great deal to be done, to make way for Christ into a soul, and nothing is more needful than the discovery of sin, and a conviction that we cannot be saved by our own righteousness. The way of sin and Satan is a crooked way; but to prepare a way for Christ, the paths must be made straight, ( Hebrews 12:13 ) . Those whose business it is to call others to mourn for sin, and to mortify it, ought themselves to live a serious life, a life of self-denial, and contempt of the world. By giving others this example, John made way for Christ. Many came to John's baptism, but few kept to the profession they made. There may be many forward hearers, where there are few true believers. Curiosity, and love for novelty and variety, may bring many to attend on good preaching, and to be affected for a while, who never are subject to the power of it. Those who received John's doctrine, testified their repentance by confessing their sins. Those only are ready to receive Jesus Christ as their righteousness, who are brought with sorrow and shame to own their guilt. The benefits of the kingdom of heaven, now at hand, were thereupon sealed to them by baptism. John washed them with water, in token that God would cleanse them from all their iniquities, thereby intimating, that by nature and practice all were polluted, and could not be admitted among the people of God, unless washed from their sins in the fountain Christ was to open, ( Zechariah 13:1 ) .
“Desert,” in Greek eremos, hence hermit. St. John the Baptist is praised by St. John Chrysostom, as a perfect model, and the prince of an Eremitical life. (Hom. i. in Mar. and hom. i. in J. Bap.) Several sectarists do not approve of what St. Chrysostom advances in favour of an ascetic life, and doing penance for past sins. (Bristow) — Do penance.[1] Beza would have it translated repent. We retain the ancient expression, consecrated in a manner by the use of the Church; especially since a true conversion comprehends not only a change of mind, and a new life, but also a sorrow for past offences, accompanied with self-denials, and some severities of a penitential life. — The kingdom of heaven, which many times signifies the present condition of Christ’s Church. (Witham) — In this and other places of holy writ, instead of “do penance,” Protestants give “repent ye;” but general use has rendered metanoia, by pœnitentia, or penance; and in this text, not any kind of penance, or grief for sins committed, but that which is joined with a desire of appeasing Him who has been offended by sin; and this also by some external signs and works. For as many as heard this metanoeite, obeyed the voice, received from him the baptism of penance, confessed their sins, and it was said to them: Bring forth fruit worthy of repentance, ver. 8. Therefore, all this was contained in the penance preached by the baptist. And here we must not omit, that while sectarists preach faith alone, both the baptist and Jesus Christ begin their ministry with practising and preaching penance. (Tirinus) — Pœnitentiam agite, metanoeite. Which word, according to the use of the Scriptures and the holy fathers, does not only signify repentance and amendment of life, but also punishing past sins by fasting, and such like penitential exercises. (Challoner)
1. The doctrine he preached was that of repentance (v. 2); Repent ye. He preached this in Judea, among those that were called Jews, and made a profession of religion; for even they needed repentance. He preached it, not in Jerusalem, but in the wilderness of Judea, among the plain country people; for even those who think themselves most out of the way of temptation, and furthest from the vanities and vices of the town, cannot wash their hands in innocency, but must do it in repentance. John Baptist's business was to call men to repent of their sins; Metanoeite—Bethink yourselves; "Admit a second thought, to correct the errors of the first—an afterthought. Consider your ways, change your minds; you have thought amiss; think again, and think aright." Note, True penitents have other thoughts of God and Christ, and sin and holiness, and this world and the other, than they have had, and stand otherwise affected toward them. The change of the mind produces a change of the way. Those who are truly sorry for what they have done amiss, will be careful to do so no more. This repentance is a necessary duty, in obedience to the command of God (Acts 17 30); and a necessary preparative and qualification for the comforts of the gospel of Christ. If the heart of man had continued upright and unstained, divine consolations might have been received without this painful operation preceding; but, being sinful, it must be first pained before it can be laid at ease, must labour before it can be at rest. The sore must be searched, or it cannot be cured. I wound and I heal.
2. The design and intention of Christ's appearing, which they were now speedily to expect. When it was prophesied that John should be sent as Christ's forerunner (Mal 3 1, 2), it immediately follows, The Lord, whom ye seek, shall suddenly come, and shall sit as a refiner, v. 3. And after the coming of Elijah, the day comes that shall burn as an oven (Mal 4 1), to which the Baptist seems here to refer. Christ will come to make a distinction,
Isaias spoke these words of the deliverance of the Jews from Babylon; but this was a figure of the freedom of mankind through Jesus Christ. The Jews expected Elias would come in person to prepare the ways of the Messias; but John the Baptist was raised up by God in the spirit and power of Elias, to precede the first coming of Jesus Christ, as Elias in person was to precede the second coming of this divine Saviour.
