Clean up your act, not just your image. The protester's sign reminds me of what Jesus said to the Pharisees. Jesus was referring to the careful and technically exact ritual of handwashing that Pharisees practiced before sitting down to a meal. They washed before eating and between courses not for cleanliness reasons, but because they prided themselves in fulfilling their ceremonial law. Their image was good, but their act was bad.
Religion never changes the heart of the problem.
It deals with surface issues. Prayers, communions, confirmations, baptisms, or volunteering for church causes may look good. Standing on form, however, won't fool God. Trusting Christ changes the heart. It brings the Source of love within us.
