{3} Bring forth therefore fruits meet for repentance:

(3) True repentance is an inward thing which has its seat in the mind and heart.

People's New Testament

3:8 Bring forth therefore fruits meet for repentance. There is no repentance whatever unless there is a change of life as the result. The change of life is the proof of the change of heart.

Wesley's Notes

3:8 Repentance is of two sorts; that which is termed legal, and that which is styled evangelical repentance. The former (which is the same that is spoken of here) is a thorough conviction of sin. The latter is a change of heart (and consequently of life) from all sin to all holiness.

King James Translators' Notes

meet...: or, answerable to amendment of life

Jamieson-Fausset-Brown Bible Commentary

8. Bring forth therefore fruits-the true reading clearly is "fruit";

meet for repentance-that is, such fruit as befits a true penitent. John now being gifted with a knowledge of the human heart, like a true minister of righteousness and lover of souls here directs them how to evidence and carry out their repentance, supposing it genuine; and in the following verses warns them of their danger in case it were not.

Matthew Henry's Concise Commentary

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.
