As a follower of Jesus, it is not enough for us to just feel sorry for something. Our sorry needs to lead to repentance.
Repentance includes regret or remorse over a past thought or action, but in its fullest sense, it represents “a complete change of orientation involving a judgment upon the past and a deliberate redirection for the future” (Note 1). Repentance, then, is a change in both thinking and action. 2 Corinthians 7
