Benefits of non-corporal

Supposedly being a spirit implies one does not have a physical body. This may imply that it does not have a place in the physical universe's casual order (does not participate in cause and effect).

As such it is possible that a spirit may be able to foresee (and maybe influence) future events more clearly by the mere fact that they are (ostensibly) not participating in the casual order of this physical universe, so it does not violate the usual "laws" of cause and effect.
