Charles H. Spurgeon on Psalms 139:6

Such knowledge is too wonderful for me. There is a mystery about the Divine Omnipresence, which we do not learn to solve, after years of meditation. As God is a simple spirit, without dimensions, parts, or susceptibility of division, he is equally, that is, fully, present at all times in all places. At any given moment he is not present partly here and partly in the utmost skirt of the furthest system which revolves about the dimmest telescopic star, as if like a galaxy of perfection he stretched a sublime magnificence through universal space, which admitted of separation and partition; but he is present, with the totality of his glorious properties in every point of space. This results undeniably from the simple spirituality of the Great Supreme. All that God is in one place he is in all places. All there is of God is in every place. Indeed, his presence has no dependence on space or matter. His attribute of essential presence were the same if universal matter were blotted out. Only by a figure can God be said to be in the universe; for the universe is comprehended by him. All the boundless glory of the Godhead is essentially present at every spot in his creation, however various may be the manifestations of this glory at different times and places. Here we have a case which ought to instruct and sober those, who, in their shallow philosophy, demand a religion without mystery. It would be a religion without God; for "who by searching can find out God?" —James W. Alexander, in "The (American) National Preacher", 1860.
