We all have cute little nicknames we give to our kids and grandkids, whether it's a hyphenated tag-on to their name or a nickname. In our family, some of the names are ZZ, Tweet, Peanut, etc. I won't tell you who is who, but they are all cute, affectionate names that we, as parents or grandparents, give to them. Sometimes they stick into adulthood and sometimes we shed them if we can and as soon as possible!
Jesus is known by many names. Isaiah said that he will be called Wonderful Counselor, Mighty God, Everlasting Father, and the Prince of Peace. His name is the name of above all names. Let your name or actions be reflective of the name above all names when you reach the age of accountability so that you will be an effective witness for him.
Matthew 16:18 (NLT) - "Now I say to you that your are Peter (which means 'rock'), and upon this rock I will build my church, and all the powers of hell will not conquer it."
