Amen, Jim! This is the result of the grace of God he allowed into His heart. It began that night when Jesus refused to allow him to think he was going to heaven the way he was. Nicodemus wanted to discuss "other things", but Jesus pointedly told him he was a Laodicean, thinking he was "rich and increased with goods," not knowing he was "miserable, wretched, poor, and blind, and naked." Jesus spoke words Nicodemus could not misunderstand. He was in a lost condition. He was humiliated. But, Jesus spoke in such a manner that He got through to Nicodemus. He knew Jesus loved him, and he realized what was being said was true.
As you point out Jim, Jesus knew the heart of Nicodemus. He knew it was not surrendered to God, but He also knew Nicodemus was seeking truth. He knew it was fertile ground. As it was in that day, so it is today. This chapter will benefit all of Christianity, for the great majority are unconverted. Many will be eternally lost, others if they will yield to the Holy Spirit, if they will learn of Jesus, they will be converted.
There is temptation to point out so much truth presented in the chapter, but to not get to the bottom is to not understand the great need of the church today.
Instead of recognizing this salutation, Jesus bent His eyes upon the speaker, as if reading his very soul. In His infinite wisdom He saw before Him a seeker after truth. He knew the object of this visit, and with a desire to deepen the conviction already resting upon His listener’s mind, He came directly to the point, saying solemnly, yet kindly, “Verily, verily, I say unto thee, Except a man be born from above, he cannot see the kingdom of God.” John 3:3, margin.
Nicodemus had come to the Lord thinking to enter into a discussion with Him, but Jesus laid bare the foundation principles of truth. He said to Nicodemus, It is not theoretical knowledge you need so much as spiritual regeneration. You need not to have your curiosity satisfied, but to have a new heart. You must receive a new life from above before you can appreciate heavenly things. Until this change takes place, making all things new, it will result in no saving good for you to discuss with Me My authority or My mission.
Nicodemus had heard the preaching of John the Baptist concerning repentance and baptism, and pointing the people to One who should baptize with the Holy Spirit. He himself had felt that there was a lack of spirituality among the Jews, that, to a great degree, they were controlled by bigotry and worldly ambition. He had hoped for a better state of things at the Messiah’s coming. Yet the heart-searching message of the Baptist had failed to work in him conviction of sin. He was a strict Pharisee, and prided himself on his good works. He was widely esteemed for his benevolence and his liberality in sustaining the temple service, and he felt secure of the favor of God. He was startled at the thought of a kingdom too pure for him to see in his present state.
The figure of the new birth, which Jesus had used, was not wholly unfamiliar to Nicodemus. Converts from heathenism to the faith of Israel were often compared to children just born. Therefore he must have perceived that the words of Christ were not to be taken in a literal sense. But by virtue of his birth as an Israelite he regarded himself as sure of a place in the kingdom of God. He felt that he needed no change. Hence his surprise at the Saviour’s words. He was irritated by their close application to himself. The pride of the Pharisee was struggling against the honest desire of the seeker after truth. He wondered that Christ should speak to him as He did, not respecting his position as ruler in Israel.
Surprised out of his self-possession, he answered Christ in words full of irony, “How can a man be born when he is old?” Like many others when cutting truth is brought home to the conscience, he revealed the fact that the natural man receiveth not the things of the Spirit of God. There is in him nothing that responds to spiritual things; for spiritual things are spiritually discerned.
But the Saviour did not meet argument with argument. Raising His hand with solemn, quiet dignity, He pressed the truth home with greater assurance, “Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.” Nicodemus knew that Christ here referred to water baptism and the renewing of the heart by the Spirit of God. He was convinced that he was in the presence of the One whom John the Baptist had foretold.
Jesus continued: “That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.” By nature the heart is evil, and “who can bring a clean thing out of an unclean? not one.” Job 14:4. No human invention can find a remedy for the sinning soul. “The carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.” “Out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies.” Romans 8:7; Matthew 15:19. The fountain of the heart must be purified before the streams can become pure. He who is trying to reach heaven by his own works in keeping the law is attempting an impossibility. There is no safety for one who has merely a legal religion, a form of godliness. The Christian’s life is not a modification or improvement of the old, but a transformation of nature. There is a death to self and sin, and a new life altogether. This change can be brought about only by the effectual working of the Holy Spirit.
Nicodemus was still perplexed, and Jesus used the wind to illustrate His meaning: “The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is everyone that is born of the Spirit.”
The wind is heard among the branches of the trees, rustling the leaves and flowers; yet it is invisible, and no man knows whence it comes or whither it goes. So with the work of the Holy Spirit upon the heart. It can no more be explained than can the movements of the wind. A person may not be able to tell the exact time or place, or to trace all the circumstances in the process of conversion; but this does not prove him to be unconverted. By an agency as unseen as the wind, Christ is constantly working upon the heart. Little by little, perhaps unconsciously to the receiver, impressions are made that tend to draw the soul to Christ. These may be received through meditating upon Him, through reading the Scriptures, or through hearing the word from the living preacher. Suddenly, as the Spirit comes with more direct appeal, the soul gladly surrenders itself to Jesus. By many this is called sudden conversion; but it is the result of long wooing by the Spirit of God,—a patient, protracted process.
While the wind is itself invisible, it produces effects that are seen and felt. So the work of the Spirit upon the soul will reveal itself in every act of him who has felt its saving power. When the Spirit of God takes possession of the heart, it transforms the life. Sinful thoughts are put away, evil deeds are renounced; love, humility, and peace take the place of anger, envy, and strife. Joy takes the place of sadness, and the countenance reflects the light of heaven. No one sees the hand that lifts the burden, or beholds the light descend from the courts above. The blessing comes when by faith the soul surrenders itself to God. Then that power which no human eye can see creates a new being in the image of God.
There is no excuse for the church today to not understand we must a new heart cleansed from sin.
There was no excuse for the blindness of Israel in regard to the work of regeneration. Under the inspiration of the Holy Spirit, Isaiah had written, “We are all as an unclean thing, and all our righteousnesses are as filthy rags.” David had prayed, “Create in me a clean heart, O God; and renew a right spirit within me.” And through Ezekiel the promise had been given, “A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh. And I will put My Spirit within you, and cause you to walk in My statutes.” Isaiah 64:6; Psalm 51:10; Ezekiel 36:26, 27.
Now that Nicodemus understands his lost condition, knowing he needs a "new heart" cleansed from sin, what must he do in order to be converted? It is the great question to be answered today.
How, then, are we to be saved? “As Moses lifted up the serpent in the wilderness,” so the Son of man has been lifted up, and everyone who has been deceived and bitten by the serpent may look and live. “Behold the Lamb of God, which taketh away the sin of the world.” John 1:29. The light shining from the cross reveals the love of God. His love is drawing us to Himself. If we do not resist this drawing, we shall be led to the foot of the cross in repentance for the sins that have crucified the Saviour. Then the Spirit of God through faith produces a new life in the soul. The thoughts and desires are brought into obedience to the will of Christ. The heart, the mind, are created anew in the image of Him who works in us to subdue all things to Himself. Then the law of God is written in the mind and heart, and we can say with Christ, “I delight to do Thy will, O my God.” Psalm 40:8.
Yet, so many refuse to look that they may live. It is such a simple gospel that we have been given. It would be good if we were to spend a thoughtful hour a day contemplating the life of Christ. Then we would know our Savior and would gladly give Him all that we have and all that we are. Then, would the whole heart be cleansed. This is what happens at conversion. Yes, many have been taught otherwise, and this is why so many remain in a Laodicean condition believing they are saved.
