Apostle John is the only one of the Disciples that mentions Nicodemus.  Apostle John is the only one of the Disciples that deals with the subject of being born again that Yeshua discussed with Nicodemus.  Being born again means to be born of Elohim or born from above.  Being born again is a supernatural occurrence that takes place.  There is an internal change that causes an external manifestation.  How do we know when a person is truly born again?  First and foremost, they receive Yeshua as the Messiah.  Second, being born again is a process of becoming.  We began as babes and grow to maturity or perfection in Messiah.  Yeshua says, “Take My yoke upon you and learn of Me.”  What are we learning?  We are learning of Him from His Word; the Word that became flesh.  Life is in His Word!  If His Word is in you, then life is in you.  If life is in you, and His Word is life, then what’s going to come out of you?  His Word!
