Not being a Christian, I am loath to correct this, but I must.
Repentance is not about ceasing to sin; it's about trying to cease to sin, and being genuinely regretful when you fail (because you will). This I do agree with, to the point where I think Christianity should be called Paulianity.
You sound like someone who has been influenced by the typical Christian conception of repentance.
Following is an explanation of the standard of repentance in Judaism:
Teshuva (Repentance)
Teshuvá is the key concept in the rabbinic view of sin, repentance, and forgiveness. The tradition is not of one mind on the steps one must take to repent of one's sins. However, almost all agree that repentance requires five elements: recognition of one's sins as sins (hakarát ha-chét'), remorse (charatá), desisting from sin (azivát ha-chét'), restitution where possible (peira'ón), and confession (vidúi).
"Recognition of one's sins as sins" is an act of one's intelligence and moral conscience. It involves knowing that certain actions are sinful, recognizing such actions in oneself as more than just lapses of praxis, and analyzing one's motives for sin as deeply as one can. For example, stealing from someone must be seen not only as a crime but also as a sin against another human and a violation of God's demands of us within the covenant. It also involves realizing that such acts are part of deeper patterns of relatedness and that they are motivated by some of the most profound and darkest elements in our being.
"Remorse" is a feeling. It is composed of feelings of regret, of failure to maintain one's moral standards. It may also encompass feelings of being lost or trapped, of anguish, and perhaps of despair at our own sinfulness, as well as a feeling of being alienated from God and from our own deepest spiritual roots, of having abandoned our own inner selves.
"Desisting from sin" is neither a moral-intellectual analysis nor a feeling; it is an action. It is a ceasing from sin, a desisting from the patterns of sinful action to which we have become addicted. Desisting from sin involves actually stopping the sinful action, consciously repressing thoughts and fantasies about the sinful activity, and making a firm commitment never to commit the sinful act again.
"Restitution" is the act of making good, as best one can, for any damage done. If one has stolen, one must return the object or pay compensation. If one has damaged another's reputation, one must attempt to correct the injury to the offended party.
"Confession" has two forms: the ritual and the personal. Ritual confession requires the recitation of the liturgies of confession at their proper moments in the prayer life of the community. Personal confession requires individual confession before God as needed or inserting one's personal confession into the liturgy at the designated moments. The more specific the personal confession, the better.
A person who follows these steps to teshuva is called a "penitent" (chozér be-teshuvá).
The tradition is quite clear, however, that recognition of sin, remorse, restitution, and confession, if they are done without desisting from sin, do not constitute teshuva. Without ceasing one's sinful activity, one has only arrived at the "preliminaries to teshuva" (hirhuréi teshuvá). Actual desisting from sin is what counts.

What you define as "repentance" is the typical Christian conception of repentance. As I said, they do not believe in genuine repentance.
To understand genuine repentance, let's start with Ezekiel who was one of the late OT prophets. Following is the standard for repentance set by God according to Ezekiel.
Ezekiel 18
21“But if a wicked person turns away from all the sins they have committed and keeps all my decrees and does what is just and right, that person will surely live; they will not die. 22None of the offenses they have committed will be remembered against them. Because of the righteous things they have done, they will live...
24“But if a righteous person turns from their righteousness and commits sin and does the same detestable things the wicked person does, will they live? None of the righteous things that person has done will be remembered. Because of the unfaithfulness they are guilty of and because of the sins they have committed, they will die...
30“Therefore, you Israelites, I will judge each of you according to your own ways, declares the Sovereign Lord. Repent! Turn away from all your offenses; then sin will not be your downfall. 31Rid yourselves of all the offenses you have committed, and get a new heart and a new spirit. Why will you die, people of Israel? 32For I take no pleasure in the death of anyone, declares the Sovereign Lord. Repent and live!
Clearly the standard for repentance set by God is that the individual no longer commits sin. Those who repent and no longer commit sin will "live". Those who do not repent and continue to sin will "die".
The gospel preached by Jesus is consistent with this standard of repentance. Those who repent and no longer commit sin will "live". Those who do not repent and continue to sin will "die".
Yet the vast majority of Christians seem to have a lower standard for repentance. Some seem to have a much lower standard for repentance.
This I do agree with, to the point where I think Christianity should be called Paulianity.
And because Christianity is
Paulianity, the standard for repentance is what is consistent with
Paulianity. Not what is consistent with the gospel preached by Jesus.
