If the significance of the Spiritual Rebirth had not been missed by Jesus' disciples and the Apostle Paul, humanity would most certainly be functioning in a different 'head space' than is the case today! Christianity would in all likelihood, be the one and only religion on the Planet. Since the 'fall' of man, men have searched in vain for God. Never realizing that man himself is an individualized manifestation of the Creative Mind of the Universe. When God created 'man', He named the 'man' He created 'Adam'. But Adam, had no idea what manner of being he was. Nor did his 'helpmeet' know that she too was God individualized. Creating 'man', was Gods way of creating God's! Through procreation, they could bring forth 'children' 'after their kind' (children of God!) Children capable of functioning as Christ's, as sons and daughters of God! But Adam and Eve did not know that they were children of God. And because they functioned 'as' men and 'ate of the fruit of the tree of the knowledge of good and evil, they lost what awareness they might have had; bringing about their fall! And, lest they should live forever in their sins, they were responsible for 'driving themselves ' from the Garden of Eden. Not only did they lose the awareness of being God's; they denied themselves an ETERNAL reality! A 'man' or a 'woman', are the only organisms on Earth that embody the capacity to by pass physical death! Providing they function as God! Should they choose instead to function as a 'man', (as a 'human' being) they shall die as a 'man'! This is the state (the consciousness) in which the whole of humanity functions to this day! All because Adam and Eve chose to walk as 'men', and all because Jesus' disciples (and Paul) failed to grasp the significance of the Spiritual Rebirth!
That men might come to see that a 'man' is but the Mind of God embodied, has been Gods quest for humanity since the creation of the species! It was Gods purpose that man might realize this when He warned Adam not to eat of the fruit of the tree of the knowledge of good and evil. For in doing so, they automatically denied the Omnipresence of God (automatically denying themselves an Eternal reality!) And it was His never ending desire that we should come to realize what manner of beings we are, that caused Him to reveal to Mary that the child she would bring forth, would show mankind the way of man's salvation! Mary did not give birth to 'Jesus'! Mary was made to see that the child she would give birth to was God (the Father) in the infant stage of development! (And she was instructed to name him "Jesus" because the name Jesus means God with us!) It was this she taught her child from the moment of His conception! It was His faith in what His Mother told Him that inspired Him to function as God! In that consciousness, He healed the sick, made the blind to see and the cripples walk, fed the multitudes, raised the dead, was transfigured and ascended into the Heavens as a living Spiritual being! His main purpose was to show humanity what manner of beings so called 'human beings 'were'! He did His best to get His disciples to see that God was the "I" within them; that 'man' and God were (are) One! (What you see me do, you can do also.) But none of His disciples realized this! Proof of this can be seen where Phillip said 'show us the Father, and it sufficeth us' (Jn.14-8)! Nor did the Apostle Paul see it! When the keeper of the prison asked Paul and Silas (Acts 16.30-31) 'what must I do to be saved', they said 'Believe 'on' the Lord Jesus Christ, and thou shalt be saved and thy house'. Proof that none of them had come to realize that God and 'man' are One (One and the same!) And we can only function As God, when we realize that God is the "I" within us! Only As God, can we function as God! Only through the 'Spiritual Rebirth', through faith in the realization that God is the "I" within us, can we realize that we are sons and daughters of God! Only then can we function as God (the Father) as did He who was known as 'Jesus' of Nazareth!
But His message got misconstrued! The remark made by Paul in the book of Acts established the foundation for the concept of the Spiritual Rebirth that the Evangelical Christian Churches of the World have been promoting for the past 2100 years! And as a consequence of this misconstrued concept, men continue to function as 'men' (and die as men)! Totally oblivious of the fact that we are all One, and that God, is that One! And only when the whole of Humanity comes to realize this (that we are all One), will there be Peace on Earth! The only difference between Jesus and the rest of humanity was that He was made to see that He and God were One and the same from birth! Whereas the rest of us were taught to function as the person our parents created when they named us. Thus the necessity of the Spiritual rebirth!
Either we choose to 'die to self', in order to live together as 'sons and daughters' of God (as we were meant to do) or we die together as 'men'.
