While this is primarily a spiritual war, which must be contested in the realm of spirit; the material realm of action is a sub-division of the spiritual - so there are implications for what we do, or don't do.
But since we are living in an evil-affiliated global totalitarian System that has captured all the major social institutions; it is playing into their hands to try and fight System with System.
This means that 'traditional' forms of resistance - which posit an oppositional program against the ideological status quo; and which are based-upon 'organization' and 'planning' - are doomed to defeat - whether by assimilation (e.g. bribing and/or blackmailing the leadership) or by direct confrontation with superior force.
If you agree that the necessary spiritual future is one of individual discernment and responsibility (i.e. final participation, direct knowing, heart-thinking) - then it is exactly these modes of intuition that should be what shapes our response.
I believe that the most effective, including spiritually effective, individuals will be those whose actions are thus regulated - by their real (divine) selves and by the guidance of the Holy Ghost.
Such an individual will be unpredictable by The System; uncontrollable by standard procedures, models and tactics - and will (so long as they are genuinely affiliated with The Good), be aided by divine interventions of many invisible types.
