Knowing who you are is probably the key factor in having a stable personality, in being balanced emotionally, and in feeling connected to your world. When you know your identity, you are at peace not only with yourself, but also with the universe.
Your identity is not physical, your true identity is spiritual. It links you to God more securely than any other link you can establish, and empowers you to become the person whom God intended you should be. It also destroys every other link that sets itself up against the knowledge of God, and of his kingdom.
