He came to Jesus by night, partly from fear of his unbelieving companions, who had already taken an openly hostile stance toward Christ. Perhaps he also wished to avoid making his visit public. He did not want to increase still further the growing fame of the prophet from Nazareth.
Received by Jesus, Nicodemus says: "We," that is, the Pharisees and scribes, "know that no one can do such signs as You do unless God is with him. Therefore we acknowledge that You are a teacher come from God."
Thus Nicodemus expressed his own view, and perhaps that of several other Pharisees. He regarded Jesus as a teacher, a rabbi, a man chosen by God, perhaps even a prophet, but not the Messiah.
Nicodemus knew that John the Baptist had pointed out Jesus to those sent from the Sanhedrin as the expected Messiah. John confirmed his indication by testifying that he had seen the Holy Spirit descending upon Him. He had also heard the voice of God Himself, bearing witness that Jesus was His beloved Son.
Nicodemus certainly saw how Jesus drove the merchants from the temple. He saw Him publicly call that temple the house of His Father, and thereby call Himself the Son of God. Nicodemus undoubtedly was present at the miracles in which Jesus manifested His divine authority and power.
After all this, he, a learned Pharisee and member of the Sanhedrin, calls Jesus simply Teacher. He believes neither John's testimony, nor His own words, nor even the miracles performed by Him.
Christ knew the cause of this false opinion about Him among the Pharisees. He knew that the Pharisees, and after them all the Jews guided by them, expected a different Messiah. In the Messiah they awaited a mighty earthly king. He would conquer the whole world and make the Jews, and especially the Pharisees, rulers over all nations.
He knew that, according to the teaching of the Pharisees, every Jew would enter the Kingdom of the Messiah as its necessary member. This was because he was a Jew, a descendant of Abraham. All the more did they believe this of every Pharisee.
Knowing all this, and wishing to turn Nicodemus from the false path on which he stood to the true path, Christ begins His conversation with him by proving that something else is necessary. To enter the Kingdom of the Messiah, it is not enough to be a Jew and a descendant of Abraham. Rebirth is necessary. "Truly, truly, I say to you, unless one is born from above, he cannot see the Kingdom of God."
To understand better the meaning of the Lord's conversation with Nicodemus, we must make a brief digression.
When God created the world, He did not limit Himself to creating soulless nature alone. He is the God of the living, not of the dead (Mt 22:32; Mk 12:27; Lk 20:38). Of course, He would not have ceased to be God even if there were no living beings at all.
Yet for the world created by Him to comprehend His greatness and the wisdom of His creative work, there had to be living rational beings in the world. A rational bond had to be established between the Creator and His creation. Such a being on earth is man.
God instructed the first people how they should live in order to be worthy sons of their Creator. He revealed to them His will, the eternal and unchangeable law written, as it were, in human hearts: Love God. Love your neighbor.
When He commanded them not only to keep but also to cultivate Paradise (Gen 2:15), He made labor their duty. This law of labor was not given as punishment for sin, since they had not yet sinned. It was given as a necessary condition of happiness.
Therefore: Love God. Love your neighbor. And labor. This is the will of God, which the people created by Him were to observe. By conforming all their actions to this law, they were to form the Kingdom of God on earth. That is, they were to become a society of happy people governed by God Himself.
In this lay the purpose of their creation. In this lay their calling. If they had truly fulfilled this law of the Supreme King, a kingdom of peace, love, and goodness would have been established on earth. It would have been the true Kingdom of God, an earthly Paradise.
But the first people disobeyed God and lost the right to be members of His Kingdom. Yet they were taught that this Kingdom, this earthly Paradise, was not lost to them forever. They could return it if they fulfilled the will of God in everything.
It seemed that living according to God was not difficult. God did not require anything impossible or unbearable from people: Love God. Love your neighbor. And labor. He required nothing more. Yet the first people could not fulfill even this little.
Soon enmity arose between them, and the earth was stained with the blood of a murdered man. Other crimes followed the first murder, and sinful people fell morally lower and lower. No calamities could bring them to reason. They began to forget not only the will of God, but God Himself.
It was necessary to remind them of this will. It was proclaimed through Moses on Mount Sinai in the Ten Commandments.
The great Moses had dreamed for forty years of freeing the Jews from Egyptian slavery. He wished to form from them the Kingdom of God, governed by God Himself. Yet he was forced to admit that morally corrupted people could not precisely fulfill God's will as declared in the Ten Commandments.
Recognizing this, he made many concessions and many departures from the Sinaitic commandments. Of course, he could have abolished all laws and customs that contradicted the Ten Commandments. He could have issued new ones in harmony with them. Yet even to him this seemed impossible.
He could indeed issue new laws and compel obedience to them by fear of severe punishments. But he could not transform the human heart, corrupted through the ages. He could not reeducate and regenerate man, and make him love.
Therefore he could not restore the Kingdom of free people who love God and one another. He could not return the lost Paradise to humanity.
For this, another Man had to appear. He would not only explain to people the will of God and the true calling of man. He would also regenerate them to a new life. By the example of His own life, He would prove that precise fulfillment of God's will is possible and even easy.
Moses understood this. Therefore, in his farewell before death, foretelling the coming of such a Man, he said: "The Lord your God will raise up for you a Prophet like me from among you, from your brethren. Him you shall hear" (Deut 18:15).
After the death of Moses, the Jews sometimes repented and turned to God, and sometimes crudely turned away from Him. Yet the moments of repentance did not last long. For this, many calamities befell them.
In vain did the inspired prophets call them to God. In vain did they wish to unite them under the headship of the Supreme King. The moral fall of humanity was so terrible that only God Himself could save it.
The prophets understood this and divinely foretold the imminent coming of the Deliverer, the Reconciler: "The Redeemer will come to Zion" (Isa 59:20). The Desired One will come (Hag 2:4-7). "Rejoice greatly, daughter of Zion. Your King is coming to you" (Zech 9:9).
Yes, they all understood that people first had to be reeducated and regenerated. Only then would the renewal of the Kingdom of God be possible, and the lost Paradise be returned to humanity. They understood that such rebirth could not take place without God's help. For this, God's Messenger had to come.
The desired Christ came and began with the reeducation of corrupted people. In His Sermon on the Mount, in the so-called Beatitudes, He taught people how they should reeducate themselves. He taught how they must be regenerated in order to be worthy sons of the Heavenly Father.
They were to form the Kingdom of God on earth, or that lost Paradise whose return the best people of the ancient world had desired. Yet in His Sermon on the Mount, after giving detailed rules for regeneration and self-correction, the Lord said that rebirth is impossible by human powers alone, without God's help. Therefore, pray to God for help. Ask, and it will be given you.
It was precisely about such self-correction and rebirth that Christ was now speaking with Nicodemus. Taken separately, without connection to the Sermon on the Mount, His conversation may seem incomprehensible to someone.
Yet if we consider that what was said in the Sermon on the Mount was probably also said during the Lord's first journey to Jerusalem, and that Nicodemus may have heard it before his night conversation, then the Lord's words become fully clear. They concerned the necessity of rebirth for entering the Kingdom of God.
