if you don't know who you are anyone will give you the identity they choose for you.
In simple terms God formed you to be like him.Your identity encompasses all the abundance of being a beloved child of God.If we live out of an identity based on how God sees us, we no longer feel the need to find our worth in our external circumstances.

Our divine identity allows us to live in confidence and stability instead of changing who we are based on the opinions of others.
