The Greek word for repentance is “meta noia” which means change your mind. It does not mean change your behaviour. It also does not even mean change the direction you are going in. Both of those interpretations are works based.
No, repentance in the bible means change your mind about God. It is often accompanied by the phrase “and believe the Good News.” The Good News is that it is by grace -undeserved favour – that we are saved through faith not by works so no one can boast. The Good News is that faith is also a gift (Ephesians 2:8-9).
Just change how you think God is and realise He is love and believe He loves you.
The rest will follow.
