The thing about repentance is: it always has to be backed up by an action or a proof of change. The very word, “repent”, means to turn away from an action, behaviour or way of life, and embrace an opposite or different action, behaviour, or way of life. This is why John asked the Pharisees to produce fruits worthy of repentance – evidence in lifestyle that they have truly changed their ways. They came out in their numbers to hear him preach but his challenge to them was that of a changed lifestyle. You need to show me proof!
The preaching of repentance in the gospel must always be accompanied by the preaching of faith. This is because the natural man, at his best, is not capable of living in a way that pleases God. To be convicted and desire to change is one thing. To truly take practical steps in living differently requires the power that only Jesus can give. In the words of Jesus, “You must be born again”. To be born again or empowered to live differently requires faith in the resurrected Christ. A man turning from his sins must turn to face Jesus Christ.
