MISUNDERSTANDING
> Repentance means to 'change your life'
So many people define 'repentance' as turning your life around. The problem with such a definition is that it implies that changing our life is necessary in order to be saved.
The Bible clearly teaches two things regarding 'changing our life' and salvation...
1. No change of life (for better or worse) can save you.
We are saved by the life, death and resurrection of Jesus Christ.
2. A saved person will eventually see a change in their life.
Once they receive the Holy Spirit, they will not be able to help but change. Luther said: "We are saved by faith alone, but faith will never be alone".
THE CORRECT DEFINTION
The true definition of repentance (metanoia) means ‘to change one's mind'.
John the Baptist said: "Produce fruit in keeping with repentance". (Matthew 3:8)
Paul said: "I preached that they should repent and turn to God and prove their repentance by their deeds". (Acts 26:20)
Neither of these statements make any sense if repentance means 'to change one's life'.
Repentance happens in the heart and mind. A changed life is the fruit of repentance.

Great point for
Great point for consideration, Mark. When explaining the gospel to people I have always simplistically explained repentance as a 180º change. I have always had an understanding that real life change comes through time and sanctification, but I agree that it is prudent to explicitly distinguish between the mental commitment to change (that is, turning from one's sins and trusting in Jesus unto salvation) and the actual change in one's life: one is the gospel, the other is not (that is, it is not a requirement for justification).
