The first sentence of the Bible, Genesis 1:1, begins with a grand declaration: In the beginning God created the heavens and the earth.
It's not 'persuasion', it's 'declaration'.
The Bible says, “Therefore, because of this and that, God exists.
It doesn't start like, "You get it?"
The Bible takes for granted the existence of God and declares that God created heaven and earth.

To conclude, our lives are not just a series of comings and goings, but have a clear purpose.
The purpose is to ‘love and be loved.’
God created humans for loving relationships.
You and I were created to be loved by God, and we were created to love one another.
This is the 'reason for life' that the Bible talks about.

--- p.69

Because there is no right response to love other than love.
Religious life is not religion.
It's not even mandatory.
Religion and duty do not help our souls.
Rather, it only binds and kills our souls.
True faith is knowing that 'I am a being born to receive God's love' and enjoying it with gratitude.

God created man and gave him complete freedom.
You have given us the ability to choose freely and think freely.
He has guaranteed us a certain degree of freedom, even the freedom to reject God.

Human reason is not perfect.
There are many things that are incomprehensible and indefinable.
The concept of 'omnipotence', the ability to do whatever we want, is a fictitious concept created by our imperfect reasoning, and does not actually exist.
Is it really possible to fully explain the Creator God with such imperfect reason?

God lifts each person up and leads them to the new Garden of Eden.
In this new Garden of Eden stands a new tree of the knowledge of good and evil.
It is a cross.
And just as He did with the first human being, Adam, He demands the same thing from each of us.
It is to believe in the cross of Jesus Christ.

--- p.109

The reason is clear.
Life is boring and dull.
If you go down to the bottom of a life that seems to lack nothing, you can hear cries of hunger.
'Just a little more! Just a little more!' This is the sound of a black hole demanding a little more stimulation.
This 'great lack' of never-ending, never-ending eating drives people to extremes.

In this way, when a sin is committed, it inevitably causes some consequences and creates negative spiritual energy.
It's the energy of sin.
And just like energy in physics, the law of conservation of energy applies to this sin energy as well.
It never disappears or dies on its own.
The energy of guilt never goes away until it is completely consumed in the form of someone's 'suffering'.

--- p.178

So we call this 'original sin'.
Even if you want to stop, even if you try not to exploit, you can't.
Because the supply line was cut off.
The root of all sin lies here.
To turn away from God, to turn away from God, the source of supply, to cut off the supply line—this is the root of sin.
