Imagine a body which is completely liberated from all the things that hinder and shackle our bodies in this life. In human terms, all the redeemed will be able to dunk a basketball, bat 1000, and birdie every hole. In this life, no matter how much you practice or try, your body can hinder your goals and aspirations. It is a body adapted and geared for spiritual existence. Our resurrected body will be completely set free from the limitations and frustrations which hinder those things associated with the physical creation.
Movement can be very exciting, especially if there are no physical limitations.
The angel Gabriel was able to move from heaven to Daniel in Babylon before Daniel could even finish his prayer. A body also implies that we will remain distinct persons, and that our consciousness or individuality isn't absorbed into some huge cosmic mind or entity.
