The most important thing is life is supposed to be 'religion'. That is how Men are made - spiritually, and even biologically. Because biologically Men evolved in a religious world - and Men's responses, motivations, attitudes and behaviours were always calibrated by a religious environment.
(I use the scare quotes around religion, because the term is so ill-defined, controversial and indeed tendentious - against Christianity; but you-know-what-I-mean.)
Men are made by God so that our lives are built-around and permeated by considerations such as God or the gods, the spiritual world around us -including matters of contact and communication with that world, life beyond death, the purpose and meaning of life so-considered... and so forth.
If we look back at any pre-modern society; it is obvious that religion was (almost always, for almost everybody) the most important thing: it provided a multi-level and integrated perspective through-which all else was evaluated.
After religion was incrementally deleted from both public life, and - in effect - from personal thinking (even among the self-described religious - due to the change towards materialism-positivism-and this-worldly ideologies) Mankind entered an unprecedented world in which there was no integration overall, and where meaning and purpose were confined to micro and specialized domains, short-termist, selfish and pulling apart.
What took-over as the most important thing in life? Variously (in different times and places) national identity, leftist politics, sex and sexuality, money, status - and sometimes (briefly) idealistic devotion to work: arts, literature, science, scholarship...
At first after religion there was an age - a generation or two - or idealism and ideology. Even sex was an ideology, for a short while - for normal sex in the 60s, for abnormal sex from the 80s...
But always, soon, these ideologies became negative, oppositional, incoherent - and much weaker as motivators. None of these replacements for religion were sufficiently powerful, effective, coherent, deep-rooted or motivating.
Until in 2020 - all ideologies, all utopian hopes (whether for sex-utopia, arts or sciences, for the residual rump of church Christianity - or for any positive ideas), were suddenly discarded; and the whole world of human aspiration replaced by a mass mindless, irrational, panicky, dependent, pathetic craving for short-term personal survival at any cost.
There was no longer any compelling positive reason to live - but only negative reasons not to die, not to suffer...
Against this global, pseudo-unifying mass effect of fear (also fuelled by manufactured and false fear of climate change due to excessive CO2) - worked many individual and group negative resentments based on sex, sexuality, race, nation, church-religion etc.
And this is where we are - now. One world system organized around negative motivators concerning the birdemic and climate change; which are Big Lies. And multiple fissile and hostile negative sub-motivators based mainly on race, ethnicity, religion and the other resentments of leftism.
Absent religion; there is only one terminus, which is despair and the desire for death - which means, to the non-religious - wished-for annihilation of the self, of the soul.
All because the most important thing in life must be religion. First that must be recognized and acknowledged as a fact. Then people must 'choose their religion'...
But this time choosing religion personally, from internal evaluations, without equating religion with any external assumed-authoritative 'church' (all major denominational churches having by now demonstrated unambiguously that they are a part of the religion-deleting, negative-system of evil).
How may someone choose their religion? On the basis of what is true - of course; but the process should probably start with asking "What would I most want to be true? Now - and, most importantly, forever."
Once that is known - we can begin work to establish whether our first idea of what we most want is really what we most want; and then whether it really is true by the profoundest intuitive evaluation we can discern.
