This is what distinguishes a gnostic teacher or master from an orthodox teacher. An orthodox teacher tries to hold you down and make you fit into the box of belief and practice that has become accepted as orthodox. A gnostic teacher or master tries to help you continually grow and expand. He or she nurtures you where you are, knowing that in that way you will grow, develop, and pass into a higher plane of existence. This is gnosis.
Gnosis is growth and development eternally.
Orthodoxy is fitting into a box and being kept there. The gnostic concept of resurrection is very different than the orthodox concept. While the gnostic acknowledges a physical resurrection, a resurrection of the physical body, as being a part of our Eternal progression, we do not spend a lot of time centering in that concept because it is not of prime importance to us in our development at this time. Eventually, if we do the things we need to do now, we know that the physical resurrection will fall into its appropriate place in our development. In fact, we know that everyone who has had a physical body will be resurrected physically, so we don't really have to do anything about that.
