A span is the distance from your thumb to you little finger with you fingers spread out. My span is less than the official figure of 9-10 inches coming in at 8.5, my shoe size. I am curious if there is a correlation between your personal span size and your shoe size.
I measure picture frames, where to put a nail in the wall, and shelf space in spans. God marked off the heavens in a span!
It seems in recent decades that God is enjoying keeping the astronomers on the edge of their seats with new glimpses of his power. In the fall of 1989, newspapers reported the discovery by two Harvard astronomers of a “Great Wall” of galaxies stretching hundreds of millions of light years across the known universe. The wall is supposedly some five hundred million light years long, two hundred million light years wide and fifteen million light years thick. In case your high school astronomy has grown fuzzy, a light year is a little less than six trillion (6,000,000,000,000) miles. This Great Wall consists of more than fifteen thousand galaxies, each with millions of stars, and was described as the “largest single coherent structure seen so far in nature.”
I say “was described” because three months later in February 1990, God opened another little window for tiny man to marvel again, and the newspapers reported that astronomers have discovered more than a dozen evenly distributed clumps of galaxies stretching across vast expanses of the heavens, suggesting a structure to the universe that is so regular and immense that it defies current theories of cosmic origins. The newly found pattern of galactic matter dwarfs the extremely long sheet of galaxies, dubbed the “great wall” (now written without caps!), that was reported in November 1989 to be the largest structure in the universe. They now say the great wall is, in fact, merely one of the closest of these clumps, or regions, that contain very high concentrations of galaxies. – John Piper in The Pleasures of God
The “great walls” are all contained within a span and are all packed full of stars which God knows by name. If he so easily created them, knows them, names them, sustains them, be comforted, wait, He is able.
If His promises and comforts sound too good to be true, Behold your God, He is mighty to save.
(I had to search for a video that seemed to have genuine Hubble images, non-X-Files/Contact music, and with the absence of an alien life form agenda. Alas a testimony to our depravity that we look to the stars and think of aliens rather than the majesty of God.)
