This devotional is about Psalm 8, specifically verses 3-9.
We look back at people who lived in Old Testament times and think they were primitive. They didn’t have electricity, indoor plumbing, or climate controls. The tools they had were crude and they spent an inordinate amount of time just trying to stay alive by providing for each day’s needs for themselves and their families.
Secular people think they were even more crude than this. They think these people didn’t understand mathematics or natural laws like gravity. They think that David and his contemporaries didn’t even know what the sun and moon were. Some people in this time even worshipped those heavenly bodies as if they were gods.
Here in Psalm 8, we see that David had a much better understanding of the physical world than we might expect. He knew that the sky he looked at in the night was showing him the “heavens” (v. 3a) and that the lights he saw in those heavens were celestial bodies in the heavens just as the earth was. In other words, he saw that the earth was not like the set of a movie with everything above being an illusion or a prop. He knew that God had created a vast universe of which the earth was just one planet.
Now that we have telescopes and satellites, we see how vast the universe really is and how small we really are in comparison. But David had a sense of it which is why he marveled, “…what is mankind that you are mindful of them, human beings that you care for them?” With so much stuff in the material universe, why would God care about humanity as a group, much less the individuals in it?
I just googled the earth’s population and it is estimated at 7.8 billion people. I can’t even begin to visualize that number, much less think about knowing each person’s name, story, thoughts, and so on. Yet God knows it all and cares about each of us individually. That’s why David concluded this Psalm with, “Lord, our Lord, how majestic is your name in all the earth!” Nobody comes anywhere near his majesty.
