I kind of operate under the idea, "If it ain't broken, break it!" I am convinced God uses Perspectives to break hearts and open eyes to the world as He sees it! When we gain His perspective - we tend to live and lead differently. Where I observe God's spirit moving, I see a church leader committed to reaching neighbors and nations. This is why I am encourageing every new worker in our movement to be informed, inspired and involved by taking a Perspectives course as soon as they can. God used it to break my heart and mold it more after His heart for the whole world.
