If I get an oppurtunity to spend a day with God. I would request God to go on a world tour. Then I would watch both happy and sad people. I would ask God the reasons of prosperity and sufferings on this Earth. I would ask the reasons why all the people are in different state of their lives. When God will explain me the reasons of people's sufferings I would explain the same things to people who are suffering on this planet and then I am sure people would be able to cope up with their grief. People would realize that after every ddark night there will be bright day.
