Who Do You Think You Are?

Who Do You Think You Are?



Our Lord and Ruler,
    your name is wonderful
    everywhere on earth!
You let your glory be seen
    in the heavens above.
I often think of the heavens
    your hands have made,
    and of the moon and stars
    you put in place.
Then I ask, “Why do you care

    about us humans?
    Why are you concerned
    for us weaklings?”

Psalm 8:1-4


Who do you think you are? What a preposterous question! Of course, you know who you are! Or, do you? Consider the following.

It was a clear, cloudless night. Tending his father’s flock on a hillside, David lay down on his shepherd’s coat. Gazing at the heavenly host, David wondered: “Who am I that the Creator of this vast expanse would care about me?”

When Galileo first turned a spyglass to the heavens in 1610, he had trouble making out the rings of Saturn that are visible in inexpensive telescopes today. Advances in optics improved scientists’ views of the planets, stars, and distant galaxies, but Earth’s atmosphere still blocked much of the light for observers on the ground. Larger telescopes were (and still are) placed on high mountains, where thinner atmospheres allow clearer pictures. In 1923, German scientist Hermann Oberth first suggested that a telescope could be launched into orbit to help overcome the distortions caused by the atmosphere. As rocket launchings became more commonplace, the idea became feasible, and in 1969, approval was given for the launch of a Large Space Telescope. Soon, we discovered that Saturn had rings. Jupiter had moons. That nebulous patch across the center of the sky called the Milky Way was not a cloud but a collection of countless stars. Within but a few years, our notion of the natural world would be forever changed. A scientific and societal revolution quickly ensued. However, that was but a small beginning!





The Hubble Space Telescope can see out to a distance of several billions of light-years. A light-year is the distance that light travels in 1 year. Since light has a speed of 186,000 miles per second (light can travel about 7 times around the entire earth in 1 second!), light travels about 5,865,696,000,000 miles in just one year. You can attach 9 more zeros to the end of this to get 1 billion light-years and another one for 10 billion light-years. The farthest that Hubble has seen so far is about 10-15 billion light-years away. The farthest area looked at is called the Hubble Deep Field. (Cool Cosmos)

Of course, I know who I am!

For all of human history scientists thought they knew. But, they didn’t! (And, perhaps they never will) What if that’s the case for you … for every human being? What if you really don’t know who you are!
