A lot of people strugle with their identity and end up seeking who they are from other people. If you do not know who you are then people will make you who they want you to be.
It is imperative that one realizes their true identity because with it comes purpose. Your purpose is in your identity and so when you lose your identity youautomatically lose your purpose.
Your identity can only be found in God, and so is your purpose. Therefore, when your find God or look for God, you will find your identity and purpose in Him. Go to God for the sole purpose of asking Him who you really are and then become who God created you to be.
