Normally not people of all ages are capable of understanding the Gospel. Although God can over rule this generalisation yet by nature there is a certain stage in one's life when one is more capable of receiving the Gospel than at the other stages. This is well demonstrated by Jesus in the process of creating the Footsteps for us to tread upon even though He possessed the very Spirit of God right from His Virgin conception.

Thus, when Jesus was a child, He concentrated His efforts in explaining to the Rabbis the basis of their moral laws and the significance of the "letters" in which the very moral laws had been written. It was only when He was of the age of 30 that He offered Himself to the ideal Priest of Moses in the name of John, the Baptist, a Levi by stock, for the baptism of water that stood for and still stands for the washing off of the "sins" committed under the ignorance or the knowledge of the moral laws. Although Jesus Himself was "sinless" yet this formality was just to create the Footstep for others to follow. This fact was known to John but Jesus asked Him to go ahead for the sake of preparing the Way to Salvation for His disciples.

Significance of age in which Nature plays its role has been demonstrated by Jesus through Nicodemus and Saul, who later on became St.Paul in His honour. Thus, Nicodemus was a very old Pharisee, an experienced teacher of the moral laws, who was a clean-hearted pious person but like most of his colleagues, he too was a man of "letters". Most of them would apply the laws strict to the letters without tempering them with the "spirit" e.g the curing of crooked hand of a person on Sabbath, a holy day best celebrated by performing holy works, was highly criticised by the men of the letters.

In order to appreciate the significance of "spirit", let us distinguish between the "letters" and the "spirit" by giving an example. Now, it is written in the moral laws that if a person steals, then he should be handed over to the law keepers. But in some parts of the world, the people would let a hungry man go if he takes enough food from a farm just to fill his hungry stomach. This custom of generosity represents the "Holy spirit" of God but it cannot be written down into the law books in black and white for the clever men of letters will exploit such acts of generosity. So, in accordance with the man-made laws that are mostly obeyed and quoted by the letters, it is unlawful to steal but exceptions to these moral laws are made by tempering them with the Holy spirit.

Thus, Holy spirit is nothing else but "common sense" that only the sensible people who can handle the Treasures of God, do exercise in their daily life e.g. the Samaritan man who looked after the wounded person that had been overlooked by the other two men of "letters". Now, both Nicodemus and the young enthusiast in the name of Saul were clean-hearted pious persons who were obeying the moral laws by the letters. Yet they were both blind to "spirit" but fortunately Saul being still young was capable of receiving "His Word" without taking a physical re-birth.

The reason why Saul and not Nicodemus was capable of receiving "His Word" without taking a re-birth will become clear through an analogy that we are like plants planted by God Who in the manners of a Farmer expects us to bear fruit. Thus says Jesus in Mark 4.26-29: "This is what the Kingdom of God is like. A man scatters seed on the ground. Night and day, whether he sleeps or gets up, the seed sprouts and grows, though he does not know how. All by itself the soil(faith in God) produces corn - first the stalk, then the ear, then the full kernel in the ear. As soon as the grain is ripe, He puts the sickle to it because the harvest has come."

Thus, we are plants planted by God and our natural growth is compared with that of a "corn" plant. So, when a person is a child, he is like a plant having only the "blades". That is, the children being led by "ego" have no "spiritual ears" to hear "His Word" and that was the reason why the disciples of Jesus rebuked those who brought the little children to Him for blessing. However, as the person becomes adult or better comes of age as stressed by Jesus in John 9.21:"But how he can see now, or who opened his eyes, we don't know. Ask him. He is of age; he will speak for himself", then the person develops "ears" to hear "His Word" and it is like a corn plant that brought forth "ears" with protruding tender and sticky "silk" threads that are capable of receiving pollen grains shed by the long and feathery "tassels" that also appear at the right time on top of the stalk.

Now, a corn plant can have a varied number of ears but only a few receive pollen grains to produce fruit. Thus, those ears on which the pollen grains fall but they do not receive them are like the "sensible" people who understand "His Word" but they do not care to put It into practice. In fact, they are like the satanic people of Jerusalem to whom Christ Jesus preached "His Word" in a plain language and afterwards cautioned them that if after understanding Gospel you if you still go against "His Will", then you commit sins or rather blasphemy. Thus, the Saying goes, "For many are called but few are chosen".

That is, out of the sensible people who have ears to hear Gospel, only a few will put It into practice to receive It and to produce fruit(oil for lamps) for Salvation. This Jesus summarised in Thomas Logo 23:"I shall choose you, one out of a thousand, and two out of ten thousand, and they shall stand as a single one". Hearing of "His Word" by the sensible adults with receptive ears and producing of fruit through receiving the pollen grains of "His Word", the New Treasures, from the God-fearing Pharisees used to be the normal practice when the Pharisees were ideal as defined by Jesus in Matt.13.52: "Therefore, every teacher of the (moral)law who has been instructed about the Kingdom of God is like the (hereditary)owner(priest) of a house(temple), who brings out of his storeroom(of knowledge) New Treasures(His Word passed on in the form of Oral Torah) as well as old(the written moral laws of Moses and Abraham)".

Now, keeping in view Matt.6.24:"No one can serve two masters. Either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve both God and Mammon", the Pharisees had become greedy and materialistic and, therefore, they corrupted the moral laws of Moses in order to satisfy their material lusts. This was like making holes in the old cloth(written moral laws) that had been passed through many hands. As the Pharisees started to love Money and to hate God, God took "His Word" away from such swines; they were left only with the dead "letters" of Moses and Abraham. Therefore, such corrupt Pharisees were unable to pollinate the "ears" of the people with the grains of "His Word". In other words, the Pharisees themselves were not producing any fruit, how could they encourage the others to do so? Thus, the Pharisees through the application of moral laws by the "letters" could produce only the healthy people, the stalks, like Saul, Peter, Nicodemus, etc. but not any fruit.

Now, a healthy plant being essential for producing fruit in abundance that Jesus recommended to His disciples in Matt.23.2-3:"The teachers of the law and the Pharisees sit in Moses' seat. So, you must obey them and do everything they tell you. But do not do what they do, for they do not practice what they teach". Saul did what his teacher told him to do.

An example of the ideal Levi Priest was John, the Baptist. He loved God and not the Money. Therefore, he lived a simple celibate life in wilderness preparing people morally strong and suitable enough for Jesus to pollinate their ears with the grains of "His Word". Thus, Saul and Nicodemus were both healthy plants(stalks) but Saul being still young, the "silk" threads of his "ears" were still tender and sticky enough to receive the pollen grains of "His Word" and, therefore, he was capable of receiving "His Word" without a physical re-birth; whereas the "silk" threads of the "ears" of the old Nicodemus had not only gone dry but they had also fallen off the "ears" with the result that even if a shower of the pollen grains of "His Word" had fallen on his "ears", he would not have been able to understand and receive "His Word" to produce the fruit. Therefore, the only way that was left for Nicodemus to understand and receive "His Word" was to take a physical re-birth in order to re-produce tender and sticky receptive "silk" threads in his "ears".

The degree of spiritual blindness that the letters had produced in Saul towards "His Word" was signified by the thickness of scales that came off his eyes when Jesus opened his Fourth Eye to "Holy Spirit" through Grace. Therefore, everybody is not capable of understanding "His Word" and It cannot be learnt by the letters in the colleges and universities in the manners of other subjects but It is preached in spirit to the sensible people and It is understood through logical "Reasoning". Out of the sensible people, one who understand and multiply It through preaching are called the "wise men" and they produce fruit whilst the others who try to misuse "His Word", God not only takes away "His Word" from them but also leaves them in a state of great confusion.

Remembering that Jesus started His ministry at the age of 30, we can say that the ideal age for receiving Gospel is between 30 and 50. That is, a person below the age of 20 normally has not developed his ears to hear "His Word" whereas a person over the age of 50 is normally too old to understand "His Word" with an open mind. In fact, the children up to the age of 20 should be taught the moral laws of Moses in order to make them physically and mentally hale and hearty and morally suitable "sons" of Man(salt of the earth) for receiving the spiritual education from the roving Royal Preachers of Jesus who, unlike the present clerics, are not the "hirelings" of Mammon.

In a nutshell, obeying of the moral laws by the letters produces a healthy "stalk" but it is only the "spirit" that enables a person to understand and put into practice "His Word" for bearing fruit. The importance of the fruit has been stressed by both John, the Baptist and Jesus. John warned the people in Matt.3.10:"The axe is already at the roots of trees, and every tree that does not produce good fruit will be cut down and thrown into the fire(of hell)", whereas Jesus by making the fig tree wither fulfilled the warning of John. That is, meagre obeyance of the moral laws by the letters is not enough but rather temper your works with the Holy spirit.

Here, it is worth mentioning that the present horrific crimes that the children commit in U.K., America, etc., the so-called rich and advanced countries, are the consequences of applying the moral laws by the very letters and not tempering them with the "spirit" on which the moral laws were originally based upon.
