Jesus followed a well-known truth about how to make spiritual and social changes. He first gathered a core group of followers and instructed them in his mission and message. He brought about changes in their lives before he dared send them out to make changes in the lives of others. We change the world by changing ourselves. Personal transformation will then impact those around us. Each of us can be world-changers if we are willing to set realistic goals and exert reasonable effort. We need to carry out his effort in union with Jesus Christ for we are his co-workers.
