Nicodemus
the people is victor, a Pharisee and a member of the Sanhedrin.
He is first noticed as visiting Jesus by night (John 3:1-21) for
the purpose of learning more of his doctrines, which our Lord
then unfolded to him, giving prominence to the necessity of
being "born again." He is next met with in the Sanhedrin
(7:50-52), where he protested against the course they were
taking in plotting against Christ. Once more he is mentioned as
taking part in the preparation for the anointing and burial of
the body of Christ (John 19:39). We hear nothing more of him.
There can be little doubt that he became a true disciple.
