The strategy of evil - and how (in principle) it can be "defeated"

Evil is strategic, it has long-term plans - and these are long-term because behind evil are demons, they spirit beings, who are not mortal, and who don't need sleep. Therefore; behind evil are wills that are active 24/7 and across a timespan greater than human lives. In other words, evil can be unrelenting - when it wants to be; in a way that is impossible for humans. 

Modern Western people are materialist hence cannot understand evil, and don't believe that demons are real or possible. This is a disadvantage when it comes to understanding life, and therefore living one's life as it should be lived.   

Humans don't behave strategically, or only seldom and partially. Most people, most of the time, simply adjust to (take for granted) whatever strategy is governing their lives. They look to be successful, happy or whatever within... whatever context is given. 

For instance; nearly all modern Western people are unaware of, indifferent to, or lazily misinterpret their leaders' recent and current activity of long-term, step-by-step, purposively engineering a global and maximally-annihilative war to include their own nations. People may be very concerned by micro-issues (such as the "climate-destroying" usage of a plastic covering to laminate paper notices) - but unconcerned or disbelieving that the contextual, ongoing, strategic intent is to unleash mass destruction in their direction ASAP. 

Modern people have been systematically degraded on multiple fronts - by alienation; passivity of expectations; PSYOPS confusions, contradictory ideology and statements; by praising and encouraging negative, destructive and sinful motivations; and maximizing addiction to mass and social media - and many other things. We are unhealthy; damaged, disordered, distorted, disorientated... all to an unprecedented degree. 

The means operate in support of the ultimate end of corruption; which is at the deepest level of false and destructive metaphysical assumptions concerning the nature of reality, themselves, and the relationship - the purpose and meaning of life.  

All this (and more could be said) seems to make evil so powerful that our situation is hopeless... 

Yet Christians know that - in principle, from first assumptions - this cannot be true; because God is the Creator, and we are each a beloved child of God. 

So, we can be sure that our life will have potential for ultimate salvation, and potential for positive learning - for as long as we are sustained alive.  

But how can this work - given the vast and sleepless strategies of evil? 

It seems hopeless only in terms of the double-negative life purpose of resisting evil.  

My current best answer is therefore to frame the question in positive terns: asking what is the basis within each of us, from-which we can each pursue good?

And we can then assume that we each have within us a core self, untouchable and uncorrupted, with sufficient innate divine nature (being God's children), and sufficient capacity for receiving divine guidance (from the Holy Ghost - who is Jesus Christ). 

We cope with evil by comparing and evaluating whatever The World throws at us, with the ongoing transcendent purposes of this core self. 

When the core is (overall) orientated towards good; then the quantity, strength and variety of evil is a nuisance, maybe a horror; but cannot drive us off-course for long, or in the end. 

So long as we locate our aspirations within this self, and no matter our many and inevitable sins, errors and lapses; and because God is creating from love of us -- when we have chosen to be on God's side then nothing can touch us - not even the world-dominating power of sleepless strategic evil.
