By saying that the God is the unknowable we haven given form to God. The very existence of the word God says that people do in fact feel that to some degree or another they know God. If one looks at the word God closely enough I think you'll find that God reflects the nature of man and the worldly very closely. And if a human looks inside themselves to make sense of what they are, then looks on the world in the same manner. Than in order for them to find what it is they are looking for, there needs be more to life than simple desire. In others words if the human see the world through eyes of order in order for patterned chaos to be order there needs to be a purpose. And if the human can only see chaos then they must conclude that they themselves are also pattern chaos. But knowing this the individual than can apply force and become the purpose needed to have order. So what if God as a knowable is filling that greater need to have that root, that purpose to expel humankind beyond that of a mere beast. In that sense what if when Abraham was spear heading the trail, that faith in God meant wisdom that grants purpose. Then when the beholder has faith or wisdom enough to turn chaos into order they receive the “gift of God” life and finiteness in all it splendor. So my question is what if faith as set forth by Abraham was not belief in God at all but the path that leads to the “God wisdom”. What if faith is stepping up the duty placed on one by a seemly innate desire to have purpose and order. Then in that sense God stops being the unknown and becomes the quest for the knowable. The quest to stop leaning on God for purpose but inside to become the purpose the creator intend an individual to be; therefore fulfilling that deep seeded need to have goal-oriented order by becoming the initial cause or true order amongst chaos.
Human have a longing to have a meaningful life, a life of wonder and splendor. But they fear time and death renders everything for not. So by the inclusion of God the person receives a meaningful life and glory with little or no effort. But these humans that live in this manner as if God is the great provider are not humans at all but mere beast. Because they stepped down from the responsibility of becoming purpose as placed there by the creator, they will never change chaos into order in fact they only add to the chaos. Then we could say that this path of faith is instead a huge funnel in which to funnel the beast through and in which humans pop out the other side. But at this time the hole on the end of the funnel is small and only a very few meek individual are able to pass trough. The rest of us beast are trying to push our way to this small hole then dump enough baggage that we to may pass through and be know as humans bringers of order.
Than as bringers of order we have it within our grasp the capacity to alter the inevitable fate of our doom as dictated by a time path laid down by infinity. A doom promised to us by a witless cause and effect. Of course this type of faith is a daunting task. Once the human gets to the point where they feel that everything is for not in the face of infinity and to realize that every effort is likely worthless and pointless. Then only by faith could they move on; not faith in themselves, for the fruits of their labor will not come in this life but faith in a hope against hope that everything is for a good reason.
When I was a kid for many years I use to a say a little pray every night. Not to God I never really did believe in God. But for years kneeled in bed after the lights were out, I would look out the window and upon the first star I saw I whisper “I wish I may I wish I might I wish upon the first star I see tonight.” Then I would still myself look into my heart than with tears in my eye and my fist clinched I would look at the star and whisper “I wish everything will turn out all right.” Mainly because I knew I was gay and yet I knew or rather I believe at that time I was not suppose to be gay. In essence I was praying for unknown forces to give me happiness in a future I could not see happiness. I have always had very dark vision and to me faith is that star, a single speck of hope billions and billions of miles away.
In short, faith is the means in which we cheat death.
But perhaps this was not the message of Abraham but musing of my own wild imagination.
