Repentance is a fruit of the Spirit. It comes from the new life and heart from the new birth.
Without the Spirit one does not have the fruit of the Spirit
and no one has the Spirit without belief

And God, who knows the heart, bore witness to them, by giving them the Holy Spirit just as he did to us,”
The scriptures are quite clear and your claim is faulty
