As a teenager, you pretty much have a mind of your own, of what and how you'd like things to be.
You are created in the image of God, fearfully and wonderfully made. God may have created billions of individuals, but He gave you your own unique look, personality, interests, strengths and potential.
Some days you may feel that you are a totally different person altogether. It's adolescence - you are still formulating your identity.
Discovering your primary identity as a new creation in Christ will give your life new meaning and direction.
