According to Wikipedia, “repentance is the activity of reviewing one’s actions and feeling contrition or regret for past wrongs. It generally involves a commitment to personal change and resolving to live a more responsible and humane life. In religious contexts it usually refers to confession to God, ceasing sin against God in order to gain forgiveness. It typically includes an admission of guilt, a promise or resolve not to repeat the offense; an attempt to make restitution for the wrong, or in some way to reverse the harmful effects of the wrong.”
Biblical repentance is quite different from this definition. Repentance is not simply confession. It is not simply ceasing sin. It is not simply admitting guilt. It is not simply good intentions to do better, nor is it simply correcting wrongs. All of these aspects are certainly needed, but even all of these put together, in and of themselves, do not qualify as Biblical repentance. In its shortest definition, Biblical repentance is a joyful and God initiated desire to continually turn from idolatry of self to worship of God.
