Nicodemus, whom Jesus called the teacher of Israel couldn’t understand it. How does one get born again, is it to reenter into one’s mother’s womb and be reborn? Of course not.
It is a spiritual experience beyond the person though with the permission of the person to rework the person spiritually and alter the person’s life with clear evidence of change in the mentality and the person’s perspective on life.
I was a truant
I changed school
My suspension and then my conversion
My life was transformed supernaturally
Bad habits stopped
Not theoretical
Miracle of being born again
Jesus answered, 5“Truly, truly, I tell you, no one can enter the kingdom of God unless he is born of water and the Spirit. 6 Flesh is born of flesh, but spirit gives birth to spirit. 7 Do not be amazed that I said, ‘You must be born again.’ 8 The wind blows where it wishes. You hear its sound, but you do not know where it comes from or where it is going. So it is with everyone born of the Spirit.” John 3v5-8
