Who in Jesus Christ are you?

When we receive Jesus as our Lord,
           we are instantly changed in our spirits,
                       2 Corinthians 5:17,
but many of us aren't aware of the change
      that's taken place inside us,
so we continue to live by our physical senses
      and natural mind,
and we are oblivious to the new, born again part
      of us that has received the fullness of God.
