There is a theme in the scriptures of people being given a new name in association with finding their calling in life. This is a moment of extreme importance, usually based around a turning point, where the old person is remade into something greater.
Especially important is who it is that is giving out these new names: God or Jesus Christ, the same individuals who seek to give us a new life, a new identity, a new purpose to follow. These are the original creators of our souls, and also the creators of our new soul, after we choose to come to them.
Therefore, the question of “who am I?” can be replaced with another question, that of “who will God make me into?” Though it goes entirely against the grain of worldly philosophy, we do not make ourselves. Perhaps we choose our own destiny, but we choose it from the options that He gives us. If you ever want to really know who you are, you have to start asking Him who He thinks you are.
