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 172assurance, "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." Rom. 8:7; Matt. 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.
It is impossible for finite minds to comprehend the work of redemption. Its mystery exceeds human knowledge; yet he who passes from death to life realizes that it is a divine reality. The beginning of redemption we may know here through a personal experience. Its results reach through the eternal ages.
While Jesus was speaking, some gleams of truth penetrated the ruler's mind.
The softening, subduing influence of the Holy Spirit impressed his heart.
Yet he did not fully understand the Saviour's words. He was not so much impressed by the necessity of the new birth as by the manner of its accomplishment. He said wonderingly, "How can these things be?""Art thou a master of Israel, and knowest not these things?" Jesus asked.
Surely one entrusted with the religious instruction of the people should not be ignorant of truths so important. His words conveyed the lesson that instead of feeling irritated over the plain words of truth, Nicodemus should have had a very humble opinion of himself, because of his spiritual ignorance. Yet Christ spoke with such solemn dignity, and both look and tone expressed such earnest love, that Nicodemus was not offended as he realized his humiliating condition.
But as Jesus explained that His mission on earth was to establish a spiritual instead of a temporal kingdom, His hearer was troubled. Seeing this, Jesus added, "If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things?" If Nicodemus could not receive Christ's teaching, illustrating the work of grace upon the heart, how could he comprehend the nature of His glorious heavenly kingdom?
Not discerning the nature of Christ's work on earth, he could not understand His work in heaven.
The Jews whom Jesus had driven from the temple claimed to be children of Abraham, but they fled from the Saviour's presence because 174they could not endure the glory of God which was manifested in Him. Thus they gave evidence that they were not fitted by the grace of God to participate in the sacred services of the temple. They were zealous to maintain an appearance of holiness, but they neglected holiness of heart.
