Current Sea is the substance of things Hoped for.
The physical manifestation of things Hoped for
is the evidence of things unseen.
Faith is the process "from promise to fruition"
that allows this to happen.
To squander Current Sea or let it be taken from us is like trashing away all the tomato seeds or letting them be stolen. This forces us into the mercantile game of poverty indebtedness where we slave for money to buy tomatoes or even tomato seeds.
To Properly Utilize the Current Sea and "hold fast to it" is like saving tomato seeds. This gives us the raw material that will fruitfully nourish and sustain us.
