i sort of know what you mean LH ,but as bill observed some posts back,something like your idea of the divine being so vague as to have little meaning,i broadly agree.
in a sense i agree in that we all spring from,and are sustained by him.paul quoted greek philosophers in that respect
   ".....he be not far from everyone of us,for in him we live and move and have our being...for we are also his offspring" acts 17 v 27f.
it is clear though from the conclusion of his address to the athenians that he wanted to move them beyond that.
i certainly think it a good thing to listen and meditate but at the end of the day your opnions of God are subjective,not having an objective point of reference.you may not believe it to be entirely reliable as a reference point but it does provide an objective ref point for its believers.
