Repentance is a discovery of the evil of sin, a mourning that we have committed it, a resolution to forsake it. It is, in fact, a change of mind of a very deep and practical character, which makes the man love what once he hated, and hate what once he loved.
Repentance causes a change in the affections, which move under the will as the commander-in-chief. It metamorphoses the affections. It turns rejoicing in sin into sorrowing for sin; it turns boldness in sin into holy shame; it turns the love of sin into hatred.Ten Commandments, 207
Surely no rebel can expect the King to pardon his treason while he remains in open revolt. No one can be so foolish as to imagine that the Judge of all the earth will put away our sins if we refuse to put them away ourselves. All of Grace (116)
The New Testament word for "repentance" means changing one's mind so that one's views, values, goals, and ways are changed and one's whole life is lived differently. The change is radical, both inwardly and outwardly; mind and judgment, will and affections, behavior and lifestyle, motives and purposes, are all involved. Repenting means starting to live a new life.Concise Theology Section 60
The nature of true repentance is clearly and unmistakably laid down in holy Scripture.
It begins with knowledge of sin.
It goes on to work sorrow for sin.
It leads to confession of sin before God.
It shows itself before man, by a thorough breaking off from sin.
It results in producing a habit of deep hatred for all sin.
Above all, it is inseparably connected with lively faith in the Lord Jesus Christ. Repentance like this is the characteristic of all true Christians.Gospel of Luke Commentary
There is an evangelical repentance which lies.—1. In a true sight and sense of sin; in a sight of it, as in itself considered as exceeding sinful in its own nature, and not merely as in its effects and consequences ruinous and destructive; not only in a sight of it in the glass of the divine law, but as that is held in the hand, and seen in the light of the blessed Spirit: and in a sight of it as contrary to the pure and holy nature of God, as well as repugnant to his will, and a breach of his law; and in a view of it as it appears in the glass of pardoning love and grace.—2. In a hearty and unfeigned sorrow for it; this sorrow for it is the rather because it is against God, and that not only as a holy and righteous Being, but as good, and gracious, and merciful, of whose goodness, both in providence and grace, the sinner is sensible; the consideration of which increases his sorrow, and makes it the more intense and hearty.
There is a legal and there is an evangelical repentance.—A legal one, which is a mere work of the law, and the effect of convictions of sin by it, which in time wear off and come to nothing; for,—1. There may be a sense of sin and an acknowledgment of it, and yet no true repentance for it, as in the cases of Pharaoh and of Judas, who both said, I have sinned; yet they had no true sense of the exceeding sinfulness of sin, nor godly sorrow for it.
There is a hypocritical repentance, such as was in the people of Israel in the wilderness, who when the wrath of God broke out against them for their sins, returned unto him, or repented, but their heart was not right with him, Psalm 78:34–37; so it is said of Judah, she hath not turned unto me with her whole heart, but feignedly, saith the Lord; and of Ephraim, or the ten tribes, they return, but not to the Most High, they are like a deceitful bow, Hos. 7:16, who turned aside and dealt unfaithfully.
There is an external repentance, or an outward humiliation for sin, such as was in Ahab, which, though nothing more, it was taken notice of by the Lord, Seest thou how Ahab humbleth himself before me? and though it lay only in rending his clothes, and putting on sackcloth, and in fasting, and in a mournful way, yet the Lord was pleased to promise that the evil threatened should not come in his days, 1 Kings 21:29. And such is the repentance Tyre and Sidon would have exercised, had they had the advantages and privileges that some cities had, where Christ taught his doctrines, and wrought miracles; and of this kind was the repentance of the Ninevites, which was also regarded of God, Matt. 11:21.
It is a change of the mind for the better, and which produces change of action and conduct: this, as it is expressive of true repentance, flows from the understanding being enlightened by the Spirit of God, when the sinner beholds sin in another light than he did, even as exceeding sinful; and loaths it, and abhors it and himself for it.
repentance is a turning to God which, even though he stirs it up in us by his word and other means, is so wrought in us, notwithstanding, especially by the Holy Ghost, that with fear we love, and with love we fear our just God and merciful Lord, from whom we were turned back, being sorry now with all our hearts that with our sins, we ever offended so gracious a Father.The Decades, https://www.monergism.com/decades-ebook
When repentance is attributed to God it noteth only the alteration of things and actions done by him, and no change of his purpose and secret decree, which is immutable. Repentance with man is the changing of his will; repentance with God is the willing of a change.
There is an eternal difference between regret and repentance. Regret feels bad about past sins. Repentance turns away from past sins. Regret looks to our own circumstances. Repentance looks to God. Most of us are content with regret. We just want to feel bad for awhile, have a good cry, enjoy the cathartic experience, bewail our sin, and talk about how sorry we are. But we don't want to change. We don't want to deal with God.
Let us beware of any repentance, falsely so called, which is not of this character. Action is the very life of "repentance unto salvation." Feelings, and tears, and remorse, and wishes, and resolutions, are all useless, until they are accompanied by action and a change of life. In fact they are worse than useless. Insensibly they sear the conscience and harden the heart.
J. C. Ryle. Expository Thoughts on the Gospels
Repentance is a heartfelt sorrow for sin, a renouncing of it, and a sincere commitment to forsake it and walk in obedience to Christ.Systematic Theology
Repentance unto life is a saving grace, whereby a sinner, out of an apprehension of his sin, and apprehension of the mercy of God in Christ, does, with grief and hatred of his sin, turn from it, unto God, with full purpose of, and endeavour after, new obedience.Westminster Shorter Catechism, Question 87
Again and again, in book after book, we see descriptions of the gospel that end up relegating the cross to a secondary position. In its place are declarations that the heart of the gospel is that God is remaking the world, or that he has promised a kingdom that will set everything right, or that he is calling us to join him in transforming our culture. Whatever the specifics, the result is that over and over again, the death of Jesus in the place of sinners is assumed, marginalized, or even (sometimes deliberately) ignored. What is the Gospel?(103)
