‘Verily, verily, I say to thee, If any one may not be born from above, he is not able to see the reign of God;’ - John 3
One thing i like about these verses,
Jesus really disambiguates body/flesh/earth from spirit/above/heaven - which IMO is key to understanding most of the New Testament, and certainly Jesus' primary message.
It is spiritual reality: the reign/kingdom of God/heaven that matters to Jesus.
It is the gospel - good news - that expereince of God and spiritual reality is within us, amoung us, near us, received as a child, experienced by those in alignment with God, a treasure worth more than all the physical wealth of this world...
We can not see it or enter it by Any physical means - not by thinking or feeling, not by physical senses or action, not by following the law...
Rather we must see it and enter it spiritually - this makes no sense to the flesh, but is rather an experience one must be opened to, born to spiritually - and then one is God-consciousness - one can spiritually experience/see the reign of God/Heaven.
This must be experienced spiritually! Words do the conversation about spirit no justice, this is why Jesus used metaphors and similes, there is no direct correlation. Words are a finger pointing to the moon.
