Repentance

Stay so close to God and so aware of yourself that repentance is a frequent response.  If you never repent you are either not walking close to God or not self-aware.....or both.   Repentance (changing direction) should be a normal part of a Christian's life.  

Here is a statement that might surprise you, but it's true-  For a Christian repentance is more important than forgiveness.  

As you read that you might recoil a bit, but realize for a Christian forgiveness is finished, we are already forgiven, now we are in the ongoing odyssey of becoming like Christ and that involves repentance, not forgiveness.  Repentance is vital for a healthy walk with God.
