God sees all over this world: every man, woman, and child; every beast on earth, every bird in the air, every fish in the sea. There is not so much as a fly or worm or gnat that is unknown to God. He knows every tree, every leaf, every spire of grass; every drop of rain or dew; every single dust mote in the whole world. God sees in darkness and under ground. A thousand miles under ground is not hid from His view. God sees all that men do or say, sees their hearts and thoughts.
God knows everything past, even things a thousand years ago. He also knows everything to come, even a thousand years to come. He knows all the men that will be, and all that they will do, say, or think. This is more than all the rest: he perfectly knows Himself. God is so great that we can’t know but little of Him. Those who know most know almost nothing of God. Man’s knowledge is not large enough: it can’t reach so far as the greatness of God. A nutshell can’t contain all the waters of the sea: so, the mind of man. The angels of heaven cannot comprehend God. But God knows Him: knows Himself altogether. We are so far from knowing all of God that we know but little of ourselves: but little of our bodies, little of our souls. But God knows all things at all times; He doesn’t sleep, is not weary of minding so many things; nothing is ever out of His mind. He knows all things at once: we can look but on one thing at once, but He comprehends all things in a single glance. . .
Because God made all things, He must see and know all things: all the stars, angels, all mankind; beast, birds, fishes, flies: every part of their bodies, their eyes, their legs, every bone, every vein. He not only knows the stars, but every tree leaf and blade of grass; every drop of water and mote of dust: God must see them all when He made them; otherwise, He could not make them. Did He not know what He did? – Jonathan Edwards (1703-1758), from a sermon on Job 9.4, preached in January, 1753.
