Numbers are important and God uses numbers, multiples of numbers, special numbers and every other kind of number you can think of. God created numbers. God put all the sciences in place so that they would have measurable results and of course these measurable results are usually found in numbers.
You might wonder, if God telleth the number of the stars, whom did He tell it to? And if he calleth them all by name, what are their names? Those are good questions. The number of the stars is so big that we cannot say it, we haven't invented it yet, we don't have a way to express it. How could we? Those who have been born again understand this better than those who have not, because as we grow closer to God we get understanding that God gets bigger and as we learn more, there's more yet and as we contemplate real deep, there is deeper still. We get it.
The realm of God is beyond our comprehension. We don't have enough space to write down the number of the stars, much less their names. I'm OK with that. If I could know all there was to know about God or figure out every science to its fullest depth and end, then God would be too much like me. But that's not the case. We are made in the image of God and we are to be like God in so many ways and we are designed with the capacity to grasp God concepts, but to think that we could find the end of any is for skeptics, not believers.
Yes God did give each star a name and yes they are innumerable by our standards, but to God they are all easily accessible and discernible. If you are wondering if your problems get the same attention that the stars get, quit even thinking that way. "Are not two sparrows sold for a farthing? and one of them shall not fall on the ground without your Father. But the very hairs on your head are all numbered. Fear ye not therefore, ye are of more value than many sparrows." Matthew 10:29-31
