I can see how it might be possible for a man to look down upon the earth and be an atheist, but I cannot conceive how a man could look up into the heavens and say there is no God.
Should a man live underground, and there converse with the works of art and mechanism, and should afterwards be brought up into the open day, and see the several glories of the heaven and earth, he would immediately pronounce them the work of such a Being as we define God to be.
Thou O Spirit, that dost prefer Before all Temples th' upright heart and pure, Instruct me, for Thou know'st; Thou from the first Wast present, and with mighty wings outspread Dove-like satst brooding on the vast Abyss And mad'st it pregnant: What is in me dark Illumine, what is low raise and support; That to the heighth of this great Argument I may assert Eternal Providence, And justify the ways of God to men.
Since everything emanates from God, he is the embodied principle in every being. Each one of us is made from God. Tat twam asi - "You are That One" who is eternally blissful, that one principle manifesting itself as this variety of Creation.
