'Repentance' in the Bible

Or despisest thou the riches of his goodness and forbearance and longsuffering; not knowing that the goodness of God leadeth thee to repentance?

For no person will be justified [freed of guilt and declared righteous] in His sight by [trying to do] the works of the Law. For through the Law we become conscious of sin [and the recognition of sin directs us toward repentance, but provides no remedy for sin].

For the gifts and calling of God are without repentance.
