Who Are We to Say?

Who Are?
Who are you to tell me?

To tell me exactly who or even what I am?
Who are you to tell me?

To tell me what exactly I am?
Who are we as an entire people?

To define what we exactly can and cannot do?
Who exactly are we as people?

To say that we cannot listen to God?

Who are we to define other people, when we cannot even understand what we truly are
