Does anyone know good people in today's society that have acted as Jesus's disciples- people like Mother Teresa and Princess Diana?

In a courtroom, it would be said that the question "assumes facts not in evidence".

Everyone will probably know someone who they might feel typifies the qualities of a disciple of Jesus Christ.

And everyone may well disagree with some of the choices of others. "Princess Diana" would be a highly contentious answer. "Mother Teresa" would have a more generalized acceptance, especially amongst 1,000,000,000 Catholics, but still could be debated.
