Don't try to over-think it. Try instead just to judge the merits of an argument based on its rationality, factuality, and logic.
The whole point of those scriptures is that we’re not to worry; not that we’re not [to] work [...]
...they toil not, neither do they spin ... if God so clothe the grass of the field ... shall he [i.e., God] not much more clothe you, O ye of little faith?
Seems clear to me that Christ is saying that God will clothe us. Consider his listeners (as I'm sure Christ did): How would they have understood that statement? As some allegorical or eschatological promise about the Hereafter? No, these listeners were simple people - many of which had empty bellies. Undoubtedly, they would have interpreted his words to mean that we should not toil, nor spin, because God will [somehow] provide us with those items. There's really very little to quibble about here. Christ is using concrete language. He is not referring to "celestial raiment" (which he could have easily mentioned explicitly, had that been his intent) but rather to actual clothing.
...and all these things shall be added unto you...
Again: Not florid imagery, but concrete things will be placed at our disposal.
Take therefore no thought for the morrow...
In other words: DON'T PREPARE!
Regards,
Are you employed? Get a paycheck? Why.
But God HAS clothed me. God HAS given me a full larder. God HAS given me a nice store of food, and the things I need to get through the winter.
God HAS given me good, honest work, and the use of my hands, and the appreciation for growing things, and the ability to hunt and fish... PRAISE GOD! And if it all burnt down tomorrow, it would all come back again, as I need it, and as I am willing to participate...
I often say that in perfect faith, I should be able to sit atop Mt. Aeneas buck nekkid in the middle of winter and be perfectly content - I am still working on that. But in the mean time, Winter is a reality, and if there ain't 4 cord in the shed, I can predict that I will get mighty cold a bit later on.
