I am the way, the truth and the light... (Explained)

John 14: [3] And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also. [4] And whither I go ye know, and the way ye know. [5] Thomas saith unto him, Lord, we know not whither thou goest; and how can we know the way? [6] Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.

My understanding of this report of Jesus's teaching is that he is implicitly contrasting the new dispensation with the old. 

In the old dispensation "the way" was a highly literal "way" - it was single path (the Law) - a single life-pattern of beliefs and behaviour that every man needed to follow if he was to be favoured by God in this mortal life. 

But the old "way" made no difference to what happened to him after death - the ghostly realm of Sheol was the common destination for all Men. 

When Jesus says that he himself is the "way" this is at first a paradox - because a person cannot be a path. So Jesus means he himself is replacing the old idea of a single and specified path-through-mortal-life.  

In future, in Jesus's new dispensation; to "do the right thing", to live well; we ought to think of our relationship with the person of Jesus, because Jesus is now "the way"...

We should therefore have a relationship with Jesus instead of trying to stick to "walking" along a semi-literal, and single, legally-pre-specified, "track" through the choices and chances of this world. 

By my understanding; "the truth" seems to refer to "reality" - or how-things-are with respect to what is important. In other words; our relationship with Jesus is the most important thing, from now...

All this is assuming that we ourselves want what Jesus is offering in his new dispensation; which is described as "the life". 

The life is, in other words, being used here as shorthand for "resurrected eternal life in Heaven"; Heaven instead of Sheol. 

(And also instead of any other other alternative post-mortal situation or state - such as annihilation, depersonalized bliss, or some kind of reincarnation.) 

 

The phrase "cometh to the Father" is less clear, and may (I think) be a later interpolation. 

But "the Father" could be taken to refer to the nature of divine creation; such that "coming to the Father" would mean coming to live in perfect harmony with divine creation which is Heaven - that is to say living by love always and wholly...

Therefore being with the father might be living in the Heavenly state which is by love and without evil; and Life without coexistent death meaning something like "entropy" - i.e. disease, damage, ageing, etc.  

A loving relationship with Jesus, and intention to accept what Jesus offers, is now replacing the old conceptualization of the "way"; it follows that following Jesus is the only "way" to Heaven, there is no other "route" through life to resurrection; "no man cometh to the Father" except by the nature of his relationship with Jesus.   

Note: As background: I also understand that our relationship with Jesus is by "the Holy Ghost" - which is the spirit of the ascended Jesus as we may know it in this world and mortal life. And I also assume that although we can and should commit to love and follow Jesus in this mortal life; the actual following Jesus to resurrected eternal life in Heaven must happen (and can only happen) after death; i.e. post-mortally.
