Let me also tell you, repentance is unto something. It is repentance unto the remission of sins. In other words, without repentance you cannot have remission of sins. Not only that, repentance is unto life, meaning eternal life. Without repentance there cannot be any forgiveness of sins, and without repentance no person can experience eternal life, which is fellowship with God.
Sinners are to repent.
Every person who is proud and arrogant, who is baptized in the juice of self-esteem, can never experience forgiveness of sins and salvation. Jesus came to seek and save sinners. And the Bible declares that all are sinners. If you deny this, you will not repent and be saved. A self-righteous person can never repent and be saved.
