Long looking with admiration produces change. From your heroes you pick up mannerisms and phrases and tones of voice and facial expressions and habits and demeanors and convictions and beliefs. The more admirable the hero is and the more intense your admiration is, the more profound will be your transformation. In the case of Jesus, he is infinitely admirable, and our admiration rises to the most absolute worship. Therefore, when we behold him as we should, the change is profound.
John Piper
