We do not desire to eat gravel. Why? Because God did not design us to eat gravel. Trying to develop an appetite for a disembodied existence in a non-physical Heaven is like trying to develop an appetite for gravel. No matter how sincere we are, and no matter how hard we try, it’s not going to work. Nor should it. What God made us to desire, and therefore what we do desire if we admit it, is exactly what he promises to those who follow Jesus Christ: a resurrected life in a resurrected body, with the resurrected Christ on a resurrected Earth. -Randy Alcorn
