A valid understanding of "clairvoyance" would be clear-seeing; which could be translated into the concept of direct-knowing.
And this is part of the idea that our divine destiny - if not in this mortal life, albeit very partially, then in resurrected eternal life - is to move-towards a knowledge based on direct, experiential knowing.
This is a consequence of the dawning recognition that what might be termed public knowledge - all quasi-objective forms of indirect, societal communication, mediated by language or other symbols - cannot and should-not be relied upon.
(Of course; this 'cannot/ should-not be relied upon' applies to science, and mathematics, as much as to all other forms of public knowledge.)
Aside from the ultimate and insoluble problem that we can never be sure that we are validly receiving and understanding symbolic truth - we can in addition (and especially since 2020) see how easily public knowledge is manipulated and exploited; how quickly and effectively lies and other types of untruth can be incorporated into public knowledge and enter 'history'...
...Such that we cannot any more regard public knowledge as objective; and are thus pushed towards what God actually wants from us; which is to rely (as bottom-line) on directly-intuited knowing - from God within, and from the Holy Ghost.
Of course (if you think about it!) such knowledge is only objectively valid in its original form - as directly known; and as soon as it is systematized, as soon as it is made-into language or other symbols and communicated... then that primary truth and validity is lost, and we are back in the realm of manipulable public knowledge.
This is why it is unwise, and sometimes fatal, to try and persuade others of the validity of that which has been directly-known. Whatever we say, write, or otherwise notate; will always fail to be that direct knowledge which we actually-received - plus; how our communications are received by other people is subject to their own prior perspective and motivations.
For Christians; the age of argument, polemic and persuasion is passing; the age of clear and personal, individual statement is upon us and growing.
We need, above all, to achieve clear-seeing of-and-for our-selves; and if we then choose to render it (imperfectly) symbolically/ linguistically - it is up to 'other people' to receive it by direct knowing... or not, as the case may be.
