Expectations--Biblical Balance

Is it a good idea to keep your expectations low to manage disappointment?... Or keep them high. There is a biblical balance between the two extremes. I don't believe this to be one of my best presentations but I think the concepts here are Important to understand. See ... I just managed your expectations. Ha! My folks couldn't make it on this morning because of weather issues but I decided late that morning to teach on-line I hope I managed with God's help to say something useful.
