Jesus follows a well-known truth about how to make spiritual and social changes. He first gathers a core group of followers and instructs them in His mission and message.
He brings about changes in their lives before He dares 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.
