Psalm 8.3-5:
(3) When I look at the heavens, the work of
your fingers,
the moon and the stars, which you have
set in place,
(4) what is man that you are mindful of him,
and the son of man that you care for him?
(5) Yet you have made him a little lower than
the heavenly beings
and crowned him with glory and honor. (ESV)
A little research regarding the estimated number of planets in the universe indicates the obvious. It is too enormous to comprehend. The number is so great that it would be pointless to write down all the zeros contained in the estimate. The Bible teaches in the verses above that God made them all by His hands, and He set them all in their places. Even in the outermost reaches of the universe.
David, the psalmist of the verses above, looking into the night sky like we do, could observe that the stars are beyond understanding. And since God made them all, and God Himself is so transcendent, why is it that He takes notice of us? We all know instinctively that the distance to the stars is great. The number of stars and their remoteness leads us to realize just how little geographic space each of us occupies in the total expanse and scale of the universe. But even in our tiny stature, God has His mind and thinking on each one of us.
