When I was growing up, my father, the social historian, taught us both history and rhetoric as dinner table conversation. He would bring up a particular conflict in history, and we would have to be able to argue either side of that conflict from the point of view assigned to us. This required that we get to know the why people had various opinions and positions. And in learning this, we learned that in arguments there are always at least two sides to things, often more. So for me, every argument was an excellent opportunity to learn about people, and particularly about the person I was arguing with. It was fun. And both sides gained from the experience. Unfortunately, most people tend to view conflicts as what I call a fight. And I will avoid fights as much as possible, because they're never fun, and generally, both sides lose, not just the particular conflict, but respect for one another, and feelings get hurt.
But also think about His normal mode of being. He didn't exactly hang out with people who likely shared His points of view. But he didn't get into conflicts with them either. He talked, He taught, He listened and learned what was important to them, and where they were coming from, so that He knew how to teach them what they needed to know.
Looking at the chart you've been working on regarding relationships and where they need to be strengthened and nurtured, go ahead and ask yourself the question, WWJD, and see if you can emulate our greatest teacher in the process.
