Barna indicated that such front porch interactions could stimulate unexpected benefits. "It’s no secret that Americans spend little time thinking through the deeper applications and implications of their beliefs. In a society confronted with challenging issues such as immigration rights, gay marriage, war, and environmental crises, our positions on such matters should come from a well-conceived and deeply embraced theology of life. Sadly, most Americans react on an emotional level rather than from a worldview that is based on thoughtful convictions. Perhaps having a Mormon or Jehovah’s Witness ringing our doorbell and pushing us to explain or defend our beliefs could be a catalyst for an even deeper process of discovery - especially if we enter the conversation knowing that we probably have some substantial disagreements on core elements of faith."
