Regardless how many times a person could be born out of his mother’s womb, he would still be flesh because flesh begets flesh. So, the Lord told Nicodemus, “That which is born of the flesh is flesh” (3:6). Flesh here denotes the natural man with the natural life. Regardless of how many times we could be born of our parents, we still would be a natural man with a natural life. It can never change our nature. To be born anew is not to be born again of our parents, but to be born of God the Spirit that we may have His divine life with His divine nature, a life with a nature absolutely different from our natural life with its nature.
