Being first all the time became very annoying especially since I was shy and didn't want to be the first at anything. Eventually I determined that one day I would only marry a man whose name was in the middle to end of the alphabet. This was very important for me when I was young because I knew that I would take my husband's name and would never again have a last name ending in "A". {Honey, if you're reading this, I didn't just marry you for your last name!!! :) } I applied for a name change soon after being married in '88 and with great joy opened the envelope containing my new birth certificate with my new name. I would never have to be first again by alphabetical listing.
As to the importance of name changes, when we adopted our children, one of our greatest days was when we received the legally binding adoption papers which showed the new name we gave our children. There was a joyful feeling of permanance which filled our hearts as we saw they were ours- our family, our children. This would be the beginning of our new lives together as a family, and we looked with anticipation of the great times we would have together.
We who have given our hearts and lives to the Lord Jesus Christ have each become a new person (2Cor. 5:17) and have been adopted into the family of God (Eph. 1:4,5). We are His children forever. But one day, a day of great joy, we will have our new name given us by the Lord where we will forever, in a binding way, be with Him.
Let everyone who can hear, listen to what the Spirit is saying to the churches: Every one who is victorious... I will give to each a white stone, and on the stone will be engraved a new name that no one else knows except the one receiving it. Rev. 2:17
And they shall see his face; and his name shall be written on their foreheads... the Lord God will be their light; and they shall reign forever and ever. Rev. 22:4,5
