Yes, any flexible conduit that has live wires drawn into it must have a ground wire also installed with the "hot" conductors. The reasoning behind this rule is that the flex in the conduit is coiled and has a long length to it. The continuation of the grounding medium through the tightness of the conduit connectors to the flex was not considered a properly secured grounding system so to overcome this weakness in the grounding system, a ground wire now has to be installed.

What is the point of grounding your house?
All electrical distribution systems require a system earth ground for personnel safety. The ground for your home electrical system is likely a grounding rod, a 10 ft. copper clad steel rod driven into the ground and then bonded with a brass clamp and large bare ground wire to your panel. This provides a path to ground to dissipate errant current which can occur due to a circuit which "shorts out." Better it goes to ground than into you!
