Schultze says “As servant speakers, we first should listen and dialogue with others to clarify what they ultimately believe. We then need to begin determining why, when, and how to use God-talk, which is believers’ foundation for big-picture truth. As we speak with others and listen to their responses, some of our views might change. We might especially refine our control beliefs, thereby making us wiser speakers in the future.” This helped me in learning that we really need a good background on your audience. If not they might react very differently to some things that could be said on certain topics. Especially when talking about God. People interpret things very differently so you need to make sure you have an opened mind and do not lose the focus of some people. Also, you need to be clear when speaking about God because you do not want people to get a different idea on what you are talking about. But altogether we learn that other people's viewpoints and knowing them only makes us wiser in the long run.
