What does John 3:1-2 mean?

1  There was a man of the Pharisees, named Nicodemus, a ruler of the Jews: 2 The same came to Jesus by night, and said unto him, Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him. (John 3:1-2 KJV)

William Burkitt’s Commentary

The former part of the chapter acquaints us with that famous conference which our blessed Saviour had with Nicodemus. This man was by sect a Pharisee; which signifies a person separated and set apart for the study of the law of God, and to teach it unto others; and by calling or profession a ruler of the Jews, that is probably one of the Jews’ Sanhedrin, a chief person in their ecclesiastical court and council.

Consider we Nicodemus first as a Pharisee, which sort of men were filled with inveterate prejudice and enmity against Christ: yet from hence we may gather, that such is the efficacy of divine grace, that it sometimes convinces and converts also those that are the greatest enemies to Christ, and fiercest opposers of him. No such bitter enemies to Christ as the Pharisees; yet behold Nicodemus, a Pharisee, coming to him, convinced and converted by him!

Consider him, secondly, as a ruler of the Jews, as a person of place and power, making a figure in the world. Though they were generally the poor which followed Christ, yet some of the great and rich men of the world, as Nicodemus, a master of Israel, and Joseph of Arimathea, an honourable counsellor, are called to Christ, and received by him: lest, if he had admitted illiterate and simple men only, the world might have thought that they were deceived through their simplicity.

Observe farther, The time when Nicodemus came to Christ: It was by night, partly out of shame, lest the world should think that such a knowing man as he was, wanted instruction; and partly out of fear; he had something to lose, and therefore durst not own Christ publicly.

However, our dear Lord upbraids him not with his timorousness, but graciously condescends to instruct him in the fundamental principle of Christianity, the great doctrine of regeneration. Such is the tenderness of our compassionate Saviour, that he will not extinguish the least spark of holy fire, nor quench the smoking flax.
