I think "self-help" here means being willing to be saved. It means admitting that you are a sinner who needs redemption.
My friend, God loves everyone, so don't be afraid to be guilty and come before God. As long as there is a heart willing to repent and abandon sin.
In the Bible, the Savior Jesus himself said to sinners, "A healthy person does not need a doctor, but a sick person does. I have not come to call the righteous, but sinners. "
"I have come not to call the righteous to repentance, but to call sinners to repentance."
Salvation is completely the grace of God, which is given to all believers for nothing.
No one can get this blessing by his own merits (such as copying the Bible).
Believing in Christianity is not to join any organization, but to have a direct personal relationship with the living God.
Is to admit that you are a sinner before God and accept Christ Jesus as your savior.
When a person sincerely confesses to God and repents, and accepts the prayer of the Savior, he is already a Christian.
I recommend this friend to read a book "Wandering Sons-Eternity is Calling" to really understand Christianity, which is available online. In fact, only with true faith can people see the glory and preciousness of life, have mature values and have real wisdom in love. From it, we can find the meaning of life and live a rich and truly satisfying life. A life free from low-level desires. But also a happy and serious life in love and gratitude.
