Luke 24:46-47
46  And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day:
47  And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.

 

2 Corinthians 7:9-10
9  Now I rejoice, not that ye were made sorry, but that ye sorrowed to repentance: for ye were made sorry after a godly manner, that ye might receive damage by us in nothing.
10  For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death.
