Elder Andersen describes well what repentance is and is not. "Repentance measn more that simply a reformation of behavior. many men and women ...demanistrate great will power and discipline in overcoming bad habits.. (but) give no thoughts to the Master" he wrote.
Repentance is an attitude towards Christ.
"our reliance must be upon th Savior Jesus Christ as we find the power not just to turn away from sin but to turn towards him"
