Consciousness is indeed the key - and the problem can be approached from several directions to yield this same answer: that (here and now, in our current situation) we must become aware of that which we used to take for granted, unconsciously - and must actively and knowingly embrace what we used passively to obey.
All this need to take place in a Christian frame - because consciousness without Christianity is a curse; and will be fled from into instinct, intoxication or passive obedience (as we see). And because without God (a personal God, the creator, who loves us each personally), there can be no knowledge.
The problem is seldom presented; but when acknowledged it is usually in terms of whom we should obey... The mainstream materialist media? A particular church? Our own pleasure seeking/ suffering avoiding instincts?
None of these will suffice, none of them are acceptable or effective. Unacceptable to our deepest, intuitive selves; ineffective in terms of this modern world.
We need each to 'dig' down to expose our fundamentasl assumptions to consciousness, so that we know what we have believed; then we should either consciously endorse these assumptions as solidities upon which we can build; or reject them - replace them.
But this is not a safe path - and it is worrying how many assumptions melt-away under the spotlight of consciousness and the tireless gaze of intuition. It is likely that we will be left with fewer assumptions; at any rate that is my experience. It is almost certain that we will be in a minority of one...
But those assumptions which remain after such a process are solid; we know them, and can defend and retain them against external attack because we do not regard external attackers as valid.
We can defend them in thought - I mean. Indeed, better than that - much better - they no longer need defending... They have become ultimately unassailable.
Of course; external power can influence, perhaps control, our mortal bodies; can terrorise us, perhaps, into doing or saying this or that; but once an assumption has been exposed and made conscious and intuitively endorsed... well, then we have it forever, we can't ever again be rid of it even if we want to - because then we will know that we are only kidding ourselves, and would not be rid of it.
We can nowadays, in The West, survive and thrive only on known certainties (both known, and certain) - and this process seems to be the only way to get them.
