I'll just throw this out here. I've been told to "let God be God" when going down thought trails like this.
We aren't called to be like God (the father). We are called to be like Christ. Look at his life and emulate from there...I am offering the same advice that I have to take large heapings of myself.
We can "talk" big. However if we don't have the power to change any of these things an argument could be made that it is not our commission to involve ourselves in divine politics.
As human beings we have a tendency to exalt ourselves larger than we are. Like we can see the how something could work but do we "really" know it will work? Do we really think we know more than the Lord does?
Why doesn't he change that? Why doesn't he change this? This could work! I know it will! Maybe so...but most of these issues do not impact salvation at all really (except our personal response to them) so should the "simulations" thereof should be avoided.
Even focusing on "Global" solutions is error. How could one person that is not the Lord make executive judgments that affect 7 billion people and think that they "know"? Tis absurd.
Some of us can certainly see more than others that is true, but our sight is still quite limited. Those that can see more fall into traps of "over extending" their sight and fall into the error of pragmatic humanistic solutions.
This isn't specifically at you btw...just in general it is something I've seen in my own life.
You could start small with local politics. Almost anyone with a speaking ability and a grasp of ecumenicism can have a modest (and possibly large effect if that were his design) by being apart of resource management, policy implementation, and creative output.
I think one of the biggest issues of focusing on the "larger whole" is hey guess what? Other people have a say also, you
cannot discount what the word says about the enemy's power on this earth and that wickedness will abound. Our business should not be primarily focused on global issues but as a sub focus sure (thus local encouragement).
Anyway, think small, start small. When you think big it is highly unlikely that you will ever "start big". We must always be faithful in a little first. I've personally protested against the Lord. Not outright rebellion...but imagine capitol hill (with the court of heaven) holding up my picket sign. It's about as effective. There is a method and there is a process.
I would also encourage you to read
Genesis 15:16 (about the sin of the Amorites being not yet at its fullness) and the corresponding verses. THAT is most helpful in understanding the delay in summary judgment and immediate executive action (which did occur in other places but typically individually). You have to give people time. We are more impatient than he is...I know how it goes
Oh...rereading through my post I thought of Babylon's sins being piled as high as heaven in correlation with Genesis 15:16 and that it is not yet complete. Something to ponder/prayerfully consider.
