It is said that when somebody is resurrected to heaven that you are not resurrected a spirit person?

Your right, the bible does teach the the meek will inherit the earth. After a person dies, his spirit goes to be with Christ. The flesh and bone stays behind, so yes if you opened up the grave, the flesh and bone would still be there. There will be a resurrection however and the spirit and body will come together again and be perfect. This is when we will dwell on the earth forever - "heaven" so to speak. The earth will be back to it's intended beauty and this will be our home.
