Sabbath Rest because of Death?

In the Sabbath year the ground is allowed to lie fallow...
or rather, left to rest

in this rest it replenishes (or renews) the nutrients it needs to grow the crops again for the next 6 years

the nutrients however - i guess - would mainly come from the death of the last crops which are no longer maintained and allowed to decompose - similar to how a forest fire would severely enrich the soil

if that's a correct understanding of agriculture...

then our Sabbath is only possible because of the death of Jesus
because He dies, we can have rest in Him..
as His body is the manner in how we are renewed...
as we take Him in and now grow in Him

yea?

The Returning Word

Here's a thought experiment into some Barthian theology of Scripture..
not even sure what I make of it myself

Barth, if I understand, explains that the Scriptures 'become' the Word of God through 'personal encounter' with Jesus, via the Spirit

I wonder then if we can continue - is then the written Word a temporary thing, like the old covenant, designed to pass away?

The Word must go out, and it is not designed to stay out, but to return, and so the written Word is temporary, and must fade - it must enter the hearts and minds of men, and continue it's outgoing, creative work

Then once accomplished, it will return to the Source, the Father, where it performs its incoming, restive work... bringing the lives of those it has made with it

so then the actual book.. unlike certain other religious theologies.. is hardly eternal, but inherently old...

what do you think?
just a flight of fancy..
