What does "The One and Only Way" mean?

The riddle of the one and only way.

There is so much misunderstanding of this statement. It says (to me) that when Jesus announces this he is only stating a fact in that moment, or for that matter any moment when we encounter Jesus. When we encounter the truth we have to decide to either to ask for clarification (if we do not understand) or accept it (if we see it's true) or we will decide to reject it and deny it (based on our own wisdom or lack thereof).

10 Do you not believe that I am in the Father, and the Father in Me? The words that I speak to you I do not speak on My own authority; but the Father who dwells in Me does the works. 11 Believe Me that I am in the Father and the Father in Me, or else believe Me for the sake of the works themselves.

So we are left with the difficult task to dicern if he is true. This might demand some study and enquiry. If we're not sure, we can just suspend judgement until we manage to solve our questions. But I still believe in what he said; seek and you shall find. So there's no need for despair.

If we approach all spiritual giants in the same manner we will probably be able to learn an enormous amount and enrich our understanding what the one and only way is about.

How do we seek? Well, the way I went about it was to ponder these question trying to understand. I did not settle for rational explanations or logical answers. Intellectual grasp was not enough. I realized all Jesus spoke about is revelatory based, and can be experienced in our own being if we push hard enough. Suddenly all mysteries came to light and revealed their hidden profound truths, all relating to a life on earth here and now.

Also, no need to try to read and study Jesus in isolation. Read it also as a vital part in our historical understanding of the evolution of consciousness. The whole Bible is a journey of us as mankind learning to walk with God (Truth). And Jesus being very much a major player in the unfolding of the scheme, of God's plan. To wake us up!
