School just started up for me again today, and in my mathematics class, I'm learning about set theory. There are finite sets with a limited number of distinct elements, but there can also be infinite sets, sets that have an infinite number of elements. In order to give these sets a cardinal number designating how many element they have in them, the infinite cardinal number is used, aleph-null.
(The subscript 0 represents that it's the smallest infinity. As the number goes up—1, 2, 3, etc.—the infinity becomes larger.)
What I love so much about this is that aleph is the first letter of the Hebrew alphabet, the language that the Old Testament was written in. And then my Lord Jesus is called the Alpha and Omega, the First and the Last. I'm having trouble figuring out how to connect the dots in writing, but basically that a letter of a language God chose to use, one which Christ calls Himself, is more than appropriate for use as a representation of infinity. And who is infinite but God Himself?
Another interesting tidbit, in the Hebrew language, the aleph has no sound. It's again perfectly and wonderfully appropriate because infinity is truly inexpressible.
