Since nothing is random or uncaused, and God is our loving Father; and since this modern world is a spiritual desert - then why are we here-and-now?
Why were we placed here, why - perhaps - did we choose to be placed here and at this most unspiritual and antireligious of times?
What possible spiritual benefit can a modern life bring us?
The answer, in a nutshell is: Living here and now compels us to reach inward to our true, divine self; because other (past) sources of Christian guidance are (for nearly all of the people in the world) either absent or corrupted.
We must become active agents, we must become spiritually - Christianly - autonomous to a degree not seen before.
Our faith tells us that God would not allow any of his beloved children to be placed in this era and situation unless there was a very good reason: something of which we, personally, have great need.
Yet this situation is one in which the Christian religion is absent (from many parts of the world), or essentially abandoned and corrupted (in the developed nations). All the usual sources of guidance are tainted - tradition, scripture, hierarchical authority, philosophy... all are much more likely to do us harm than good if we go to what is most available and accept it uncritically.
We can get nowhere without discernment.
Therefore spiritual passivity is - for us, here and now - ruled-out.
When the human aspects are all tainted or unobvious, then a policy of subordination and obedience are much more likely to do us harm than good; because we would probably be serving the Enemy rather than God.
In modernity we are brought to a state of utter isolation of our selves, and a loss of confidence in the reality of the world and of that self which is all we can experience. And our self and the world is dead, inert, passive and perceived as unliving - an accident, merely an illusion or delusion of our own limitations. We cannot perceive God, Jesus, angels; and even other people are merely shadowy entities justified only be the comfort or pleasures they provide.
We have so decisively lost the ability to know the external environment, that we regard it as a product of our minds; yet our minds are (in mainstream understanding) merely temporary, contingent, arbitrary collections of brain circuits - unreliable, prone to malfunction and doomed to extinction.
This is the state of nihilism when nothing is really-real and despair is inevitable and ineradicable.
So why are we here and now?
When there is no reliable external guidance, we must look within: and must means must, because there is no alternative.
Our Loving Father, the Creator would not have placed us here unless we had the resources to attain salvation and to make steps towards theosis (becoming more divine).
Since these resources are not to be found outside us, then everything we need must be found within - and by invisible, spiritual means of communication.
Specificially, what we need to begin is found within, and everything else follows as consequnces.
We must look within to find and feel our internal spiritual compass - that which is divine and eternal within each of us; that in us which is a child of God (still merely a child, but certainly that!).
Once we have located that inner reality; then - and only then - we can look outside; look (that is) not by our senses but directly to the world of spirit: open our real selves to to direct knowing and personal revelation from God, and the personal friendship of Jesus Christ.
That is why you and I are here and now; because what we personally most need, is to learn to find God within us.
Modernity is, indeed, a harsh spiritual lesson - but presumably that was the only kind of lesson that you and I were capable of learning.
(Earlier people in earlier generations, or people in different parts of the world, have other things that they need to learn . I am here talking about a reason why living in The West, the developed nations - is the best realistically-possible thing for some people; people such as you and me.)
And of course this is a lesson each and every one of us absolutely needs to learn if we are ever to develop from the passive state of being immature, externally-driven, dependent-children of God into what he hope for us to become: active, agent, autonomous grown-up 'friends' of God (and ultimately perhaps spiritual parents in our own right); at a level where we can fully participate - Son or Daughter of God - in the great and endless divine work of love and creation.
