We are known by what we look like, it's part of our identification. If someone came and told me they were my mom, but they didn't look or sound like my mom, I would not think they were who they said they were. The same is true for our character. If we said we were so good, but others could not see the good, they would not believe us. Tigers look like tigers, sinners look like sinners. Thankfully, Jesus can come along and change our reality, but not perfectly until we see him face to face.
