So I just had a thought. In Hebrew tradition after betrothal the groom would go away to build the home for him and his bride. Jesus said I go to prepare a place for you.
Remember how he made baked fish for his disciples on the shore after His resurrection? He didn't have to. He walked through walls and changed His appearance, but He took the time to make food for His disciples who had worked hard all night and then He created another miracle so that they had full nets of fish that Peter dragged to shore. So after He ascended into heaven, is He like building the New Jerusalem by hand?
