I think I momentarily lost sanity when I took a picture of my Social Security Card, Driver's license, and credit cards as being important numbers. I tried covering up part of each number. But in the end decided that was not a wise move and could get me in lots of trouble. So that picture didn't make it to my top three.
So here goes:
Picture #1 represents our medical numbers.

Picture # 2 are fun numbers. I found many games and activities that use numbers in some fashion. But I liked this shot the best.
Picture #3 is God's Numbers. Although this book is not often listed as a favorite book of the Bible, I find it interesting that God included it as a part of Holy Scripture. It was important to Him to tell us of the specifics of how many people were in each family group. He includes the numbers in many places throughout scripture giving details of ages and many other numerical information.
