Rabbeinu Yonah opens repentance with recognition of wrongdoing, remorse, confession, and commitment to abandon the old path, treating change as a structured return.

In explanation of repentance and its principles Among the good things which God, may He be blessed, has bestowed upon His creations is the path which He prepared for them to ascend from the baseness of their actions, to escape the trap of their inequities, to hold their souls back from destruction and to remove His anger from upon them. Because of His goodness and uprightness, He has taught them and warned them to return to Him when they sin against Him - for He understands their nature, as it is stated (Psalms 25:8), "Good and upright is the Lord; therefore He shows sinners the way." [Even] if they greatly sin and rebel and act like treacherous betrayers - He does not close the doors of repentance to them, as it is stated (Isaiah 31:6), "Return, to Him to whom they have been so shamefully false." It is [also] stated (Jeremiah 3:22), "Turn back, O rebellious children, I will heal your afflictions." We are warned about repentance in several places in the Torah. It is explained that repentance is accepted even when the sinner repents because of his many troubles - how much more so [will it be accepted] if he returns because of fear or love of God - as it is stated (Deuteronomy 4:30), "When you are in distress because all these things have befallen you and, in the end, return to the Lord your God and obey Him." It is explained in the Torah that God will help those who repent beyond what their natural ability would allow; and that He renews a pure spirit within them, to reach great heights in His love - as it is stated (Deuteronomy 30:2), "And you return to the Lord your God, and you and your children heed His command with all your heart and soul, just as I enjoin upon you this day." Further, it is stated about the body of the matter (Deuteronomy 30:6), "Then the Lord, your God, will circumcise your heart and the hearts of your offspring," to acquire love for Him. And the Prophets and Writings constantly speak on the subject of repentance, such that the principles of repentance are all explained in their words, as will be explained. Know that the punishment for the sinner who delays repenting of his sin will grow much heavier for him every day. For he knows that [God's] wrath has gone forth against him and that he has an escape route from it - that escape being repentance - yet he still remains rebellious and stays within his evil. Even though it is within his power to leave from within the disorder, he does not fear the anger nor the rage. Thus, his evil is great (see also Midrash Kohelet [Kohelet Rabbah 7:15], which relates a parable illustrating this concept). And furthermore - reflect upon the evil of the one who delays repenting, as it is great. For if it were not that he had delayed - now when his impulse would confront him a second time and he have the opportunity to sin, he would recoil and sigh with a bitter heart, with anguish and worry; and his eye would weep with grief. He would [then] subdue his impulse, remember that the cup of bitterness had passed over him once and he would not drink it again. As it is stated (Psalms 4:8), "Tremble and do not sin" - its explanation is, tremble and fear and be troubled about your sinning, and do not sin again. For it mentioned their sin above [in that chapter in Psalms], when it stated (Psalms 4:3), "you sought falsehood, Selah." And its using the expression, "tremble," confirms this explanation. [As its usage is like in] (Genesis 45:24), "Do not tremble along the way"; and (Habakkuk 3:16), "I trembled where I stood." And their meaning is distress at something that passed and is still present. And it did not state (in Psalms above), "Fear," or "Flinch." But when he delays from repenting - when the sin comes to his hands, he will fall into its trap like he fell at first. And his second iniquity will be very great and his evil will rise up in front of God. For at first, he did not think that the marauding impulse would come upon him. But after he saw the weakness of his power and that his impulse had overcome him and that it is more powerful than he; he should have seen that it is unbridled, and he should have sought to increase his fear of God, to bring down His fright upon his soul, to save it from the ambush of his impulse and to protect it from its iniquity. And King Solomon, peace be upon him, said (Proverbs 26:11), "As a dog returns to his vomit, so a fool repeats his folly." Its explanation is that a dog eats disgusting things; but when he vomits them, they are more disgusting, yet he returns to eat them. Such is the matter of a fool. For he will do a disgraceful act, but when he repeats it, it is [even] more disgraceful, as we explained.
