In his book The Way of a Worshiper, the author gives the following definition of repentance:
Repentance is not a once-in-a- lifetime commitment. It’s not simply an apology with a promise to do better.
Repentance is a whole new lifestyle.
Repentance is a determination to change the way we live – to stop, turn around, and head in a new direction.
Repentance is cooperating with God in the transformation of our character.
Repentance is a heart posture that is reflected in the choices we make.
Repentance is an act of worship.
Repentance is not something that happens once at our conversion to new life in Christ. It is a mindset, a determination, to continue to turn from sin and to turn toward God from this point on until Christ comes back or we die. Repentance is an act of worship, according to the above definition.
But, like worship itself, it is an action that never ends.
