...
Repentance is turning back.
The word 'shub' in the Old Testament, meaning repentance, means to turn around, to make a U-turn.
If we are Christians, we must know repentance, if nothing else.
No, you have to know it exactly and experience it.
If you are baptized but do not die with Jesus and reach the resurrection, if you do not repent and reach the new life ruled by the Lord, you cannot enjoy the kingdom of God even if you go to church.
Perhaps that kind of faith is the most pitiful of all faiths.
I go to school but I'm at the bottom of my class, I go to the gym but I have no muscles, and my health is terrible.

...
This book consists of ten stories about how to practice repentance and ultimately enjoy the kingdom of God.
Repentance is the courage to turn back, a break from the world's rules for success, and a change of perspective.
Repentance is going against my nature, it is upstream from solving the fundamental problem, and it is breaking free from self-obsession.
Repentance is acknowledging my responsibility, riding God's wave, and acknowledging that there is no other way than prayer to seek God's will.
Ultimately, repentance is a Copernican shift in life.
It's not just about getting baptized and going to church.
It is not a life of attending Mass on Sundays and fellowshipping with people of the same faith.
We need to go further.
Repentance is a Copernican shift.
It's about living from a completely new perspective.
I conclude this manuscript with a fervent prayer that the Kingdom of God will come to all who read this book.
