Shakespeare famously wrote “What's in a name? That which we call a rose by any other name would smell just as sweet.”  He used this line in Romeo and Juliet to convey that we don't have to know someone's name to love them, which is true of course. But in many cultures, even in this modern age, the naming of a child is a careful, often hopeful choice, which often seems to be unexpectedly prophetic.
This certainly was the case in our family, each name chosen deliberately and prayerfully. In my case, I have not always lived up to the meaning of my own name, Evangeline,  but the older I get, the more I pray that my name would bring honour to HIS Name.
A well-loved chorus in my dim past was "There's a new name written down in glory, and it's mine,  oh yes it's mine." My child mind visualized my name being added in angel writing on a long scroll of the Redeemed of all ages. However, I think it is far more profound than that. Interestingly, there are several allusions in the Word to us having a name that only God knows, that it is precious and that one day, we will be shown what it is.
Perhaps it's like the private, pet names we have for the people we are closest to, names we do not routinely share with others. I know that there are names used by my beloveds, names that I hug to my deepest soul in private joy, names I would be shocked to hear from another's lips.
So when God says "I have called you by name, you are mine," my imagination soars and my spirit longs to know the name HE has given to me.
For now I see in a mirror, dimly, but then face to face. Now I know in part, but then I shall know just as I also am known. 1 Cor. 13:12
