This means that there is Truth (i.e. God, divine creation and its values) but that this cannot (any longer - although in some times and places it could) passively be absorbed by affiliation to any external institution, nation, or church authority - but must actively (with free agency) be chosen by each individual.
What is actually happening (apparently, for most people) is that a single free choice is being made to believe whatever concepts the international bureaucracy-mass media are propagating today.
Since each day's official-media story propagates first today's concept, then today's facts - and the decision has been made to believe whatever these are; there is no basis for any individual whose loyalties are to The System ever to discover incoherence or lies. Yesterday's concepts and facts are irrelevant - except when today's is saying they are not.
Thus belief is continually changing to track 'today's story'.
The only way out is to consider the fundamental assumptions that underpin 'today's story' - which entails recognizing that there is a mind behind The System.
(And, of course, it is a part of The System to deny this, and to assert that everything that happens is a consequence of non-purposive causes.)
Having assumes a mind behind The System; the individual must make a value-evaluation as to whether that System-motivation is Good or evil; on the side of God, or against (recognizing that it must, overall, be one or the other).
(And, of course, it is a part of The System that there is no God, and that reality is not a creation - but instead that ultimately all is accidental, purposeless and meaningless.)
