We all see the world in only one way: through our own eyes and no one else's. This can make agreement difficult sometimes. It causes division and hurt. In our culture today, some many feel the need to either convince others that their way of thinking is correct or that those who continue to think differently are crazy, dumb, or both. God calls us, as the church full of fellow believers, to be at peace with one another. David describes this in the psalms in some rich ways because when we do life together, we all win because of our bond in Christ.
