The Shun and my speculation regarding it

When Adam and Eve fell from grace, God shunned them away from the garden leaving them in the world of hard difficulties. 

I believe this event happened for this reason (among others):

Violation of order would invoke liabilities to exploits, if you kept on living in a "Garden" while the system was vulnerable, everything done was subject to sabotage. 

So rather than having expensive ventures being sabotaged in the end, we must diversify and always take into account exploit vulnerabilities in everything we do. Like when installing an operating system you should always have an antivirus/security management system with you. 

Ok so this is my speculation,

The order to multiply and subdue the earth (Genesis 1) was it before or after the fall? It could be after Adam and Eve were shunned, cause the reason why human beings should be so many is to brought into reality a comprehensive security system or systems that's good enough to mitigate all of the evil from the "enemy". Good enough "anti-injustice" systems

Proverbs 4:23

Keep thy heart with all diligence; for out of it are the issues of life.

The Spirit of Truth is not dismissable v.02

 And whatsoever ye do, do it heartily, as to the Lord, and not unto men;

That's Colossian 3:23

So at first it seems that people who do their job with lies get different results than those who do it Truthfully, a lot more money potentially.

For us Christians we must keep our Faith including our logic that the way things develop, things that were done in despise of the Truth would brought about irrelevance (in terms of the Truth).
