Setting our mind on heaven means we have to think like heaven thinks. Do you think the hosts of heaven are anxious and insecure about the future of planet earth? If they are not, we should not be either. Setting your mind on heaven means we are not upset by the events on earth. That doesn’t mean we ignore life on earth. It simply means we don’t look to earth for our security, our comfort, our knowledge, or our hope. For those things we must look to heaven alone.
