When Jesus said of his disciples: “The secret of the kingdom of  God has been given to you. But to those on the outside everything is said in  parables so that, they may be ever seeing but never perceiving, and ever hearing  but never understanding” (Mark 4:11-12 NIV) -- that word translated secret, is the same word translated  mystery, and makes reference to an esoteric knowledge that is beyond man's  organic comprehension.   Yet, in a state of spiritual  denial, the the modern Church attempts to ignore the implications of what these  words convey.    In explanation of the above words of Jesus, the Wycliffe  Commentary writes that: “…the initiate was instructed in  the esoteric teaching of the cult, which was not revealed to outsiders… The  mystery of the kingdom in its ultimate development is the full-orbed message of  the Gospel (Rom 16:25-26). The purpose of parables was to instruct the initiates  without revealing the items of instruction to the ones who were without. This is  in keeping with the Biblical principle that spiritual understanding is  restricted to those who have become spiritual...”  
 If, as openly stated above, it is true that Jesus taught  initiates differently than the multitude of people who he portrayed as being  "...outside",  then a true seeker must conclude that every article of faith promoted by the  Church today, would have to be totally re-evaluated.    Thus the question: What  was Jesus stating with respect to why he spoke in parables?   To ignore this  question, is to reject the whole foundational objective and revelation of the  Bible.   Jesus was stating that only those who become separate from the thinking  and ways of this world, and became true disciples of Messiah/Christ, are able to  perceive and understand the secrets of the Kingdom of God -- and in the Greek  language, this sacred Knowledge is called Gnosis.   And by the very meaning of  the word that is being presented that cannot be revealed "...to ordinary mortals.  A hidden or secret thing, not obvious  to the understanding" -- it is of the utmost importance to recognize  that what is being conveyed is the fact that "...spiritual understanding is restricted to those who have  become spiritual...”.   Why?    Because man in his organic or "natural" condition of mind, has yet to  develop the facilities of mind necessary to receive and comprehend this higher  spiritual knowledge that the biblical authors are making reference to.  
 When it is recognized that this very warning was stated by  Paul to the baptized and totally committed believers at Corinth -- i.e., “I always thank God for you because of his grace given you in  Christ Jesus. For in him you have been enriched in every way -- in all your  speaking and in all your knowledge -- because our testimony about Christ was  confirmed in you. Therefore you do not lack any spiritual gift as you eagerly  wait for our Lord Jesus Christ to be revealed” (1 Cor 1:4-7 NIV) --  the modern reader who does not pause and reflect on what this means --  personally -- to them, remains a blind man who is beyond the reach of the Gospel  message.   What is Paul stating to the believers at Corinth?   That even though  Paul himself had instructed them in the "testimony" of Christ -- and that they had received  the entire revelation of the Good News of the Gospel -- to the degree that they  were not "...lacking any spiritual gift" --  they had yet to evolve and mature those facilities of mind that would enable  them to perceive, discern and comprehend the higher reality of the soul and what  Paul portrayed as the Mystery of the Gospel.   And this is especially  demonstrated in the second chapter of the very same Epistle where Paul warns  these believers who have been given all primary historical knowledge and  testimony of Christ: “But the natural man does not  receive the things of the Spirit of God, for they are foolishness to him; nor can he know  them, because they are spiritually  discerned” (1 Cor 2:14 NKJ).    And just  as important is thee fact that Paul stated that when they complete the process  of transformation and achieve this higher level of spiritual maturity, that the  Christ will come to them and teach them -- i.e., "...as  you eagerly wait for our Lord Jesus Christ to be revealed”.    And  thus, this is the meaning of the allegorical End Times when the Kingdom (within)  comes upon the earth (the body) of the disciple/seeker.    This Spiritual  Knowledge that can only be revealed by the Lord, is called Gnosis -- i.e.,  spiritually experienced and acquired knowledge that can only be imparted to  those who have so prepared themselves that they are as virgins who have filled  their lamps with the oil of purification necessary to receive the Lord.  
 The early Christian Valentinius quoted Paul's Epistle to the  Ephesians when he made reference to Gnosis  Kardias -- or, the enlightened eyes of the heart.   "I pray also that the eyes of your heart may be enlightened in  order that you may know the hope to which he has called you, the riches of his  glorious inheritance in the saints" (Eph 1:18).   And that Paul  wanted very much to speak about the Mystery of the Gospel to the Ephesians, but  could not, is the reason he portrayed himself as an ambassador in bonds: "And for me, that utterance may be given unto me, that I may  open my mouth boldly, to make known the mystery of the gospel, for which I am an  ambassador in bonds: that therein I may speak boldly, as I ought to  speak" (see Eph 6:19-20).   And how did a seeker/disciple obtain  these enlightened eyes of the heart?   Very briefly, by fulfilling the role of a  virgin who awaits the Lord with the oil of purification -- and by becoming the  "good ground" that permits the necessary  expansion of the facilities of mind to be brought about, which enables the  seeker/disciple to be taught by the Indwelling Logos/Son of God/True Prophet.    And in the same way that in the parable of the ten virgins it was said to those  who had failed to prepair themselves with the oil of purification that "Assuredly, I say to you, I do not know you" -- even  though they believed and had called upon the Lord and was awaiting his coming,  this reality of the believer who has failed to prepare himself is futher  explored in the early Christian scripture known as the Shepherd of Hermas.    
 In the introduction of  the early Christian writing known as the Shepard of Hermas, it is written:  “The Pastor of Hermas was one of the most popular  books, if not the most popular book, in the Christian Church during the second,  third, and fourth centuries... In ancient times two opinions prevailed in regard  to the authorship. The most widely spread was, that the Pastor of Hermas was the  production of the Hermas mentioned in the Epistle to the Romans. Origen states  this opinion distinctly, and it is repeated by Eusebius and  Jerome”.   If, then, it is true that the Pastor of Hermas was  one of the most important scriptural authorities over the first four centuries,  then we can use it in our endeavor to better understand the essence of early  Christian thought.   What the Shepherd of Hermas has to say is very  important to us today, because it represents the scriptural tradition that was  taught directly to the faithful flock by the Apostles of Christ.   Thus, on the nature of scripture, in the Shepherd we find:  “I am senseless, sir, say I, and do not understand  these parables. For how she can crush out, and on the other hand save, I do not  perceive. Listen, says he. Those who have never searched for the truth, nor  investigated the nature of the Divinity, but have simply believed, when they  devote themselves to and become mixed up with business, and wealth, and heathen  friendships, and many other actions of this world, do not perceive the parables  of Divinity; for their minds are darkened by these actions, and they are  corrupted and become dried up. Even as beautiful vines, when they are neglected,  are withered up by thorns and divers plants, so men who have believed, and have  afterwards fallen away into many of those actions above mentioned, go astray in  their minds, and lose all understanding in regard to righteousness; for if they  hear of righteousness, their minds are occupied with their business, and they  give no heed at all. Those, on the other hand, who have the fear of God, and  search after Godhead and truth, and have their hearts turned to the Lord,  quickly perceive and understand what is said to them, because they have the fear  of the Lord in them. For where the Lord dwells, there is much understanding.  Cleave, then, to the Lord, and you will understand and perceive all  things”. 
 The message that is very  clear from this early Christian writing is that it is impossible to mature  spiritually, while attempting to divide oneself between the two worlds.    In our present day culture we are living proof as to the validity of the  wisdom that is portrayed in this writing -- i.e., one cannot perceive the true  meaning of the parables and the inner significance of the historical narrative  of the scriptures, while one devotes their lives to their “business, and wealth, and heathen friendships, and many other  actions of this world” -- which would include the whole array  of addictions provided by all the many leisure’s and entertainments that  captivate and control our every-day lives.   Further, do we truly do unto  others as we would want others to do unto us -- i.e., do we send our children  (the souls who were placed in our care) off to government secularized schools to  become imbued with the thinking, mindset and lifestyle of the heathen culture in  which we presently live?    
 In the Shepherd of  Hermas a reference is made to a tower, of which it is written: “And the tower, I asked, what does it mean? This tower, he  replied, is the Church. And these virgins, who are they? They are Holy Spirits,  and men cannot otherwise be found in the kingdom of God unless these have put  their clothing upon them: for if you receive the name only, and do not receive  from them the clothing, they are of no advantage to you. For these virgins are  the powers of the Son of God. If you bear His name but possess not His power, it  will be in vain that you bear His name”.    In understanding what is written, it  is most important for us to be aware of the continual message found in the  words: “If you bear His name but possess not His  power, it will be in vain that you bear His name”.    Thus, if you call yourselves Christian, but fail to purify and develop  your mind and body from the defilements of this world -- and do not possess the  true Knowledge of the Spiritual Christ -- and have not yourselves inherited the  same higher powers of mind that the Son of God promised all his followers would  possess -- then “it will be in vain that you bear  His name”.   And again, this  is demonstrated in the words spoken to those who believed upon the coming of the  Lord, and even called upon his name, but had failed to bring with them the oil  of purification, where it was stated: "Assuredly, I say  to you, I do not know you"
