Beloved, now we are children of God; and it has not yet been revealed what we shall be, but we know that when He is revealed, we shall be like Him, for we shall see Him as He is.
– 1 John 3:2
When we adopted our sons from another country, we gave them new names because they were starting a new life with us. We will also be given a new name when we start our new lives, our real lives, in heaven.
Until that day, your identity, your eternal name is unknown to you. In your earthly life, you are just starting to become the beautiful being God created you to be, a being not defined by the world, but like Christ.
