Philosophically, I agree. But.....I believe that those of us who worry and work so hard to "try to make things better" are spinning our wheels. God has already told us how deep into the sewer the Earth will go before Jesus returns to set things right. Being a believer, I do not think we will be moving towards a God-based future until He finishes the job of vanquishing Satan. All we are doing now is being a bit disobedient ("resists not evil") by presuming to try to do His job despite what He has told us is in store, and being distracted from our only usefulness to Him by concentrating on carrying the Word and tending to our own souls and being good witnesses for our families and for others.
That won't stop me from supporting Cruz (or Walker if Cruz stumbles) and trying for a more sane government, but I know that it is just an exercise in futility - He has passed the edict to us and we need to prepare ourselves and our families/children to carry His Word.
I think it helps to review history. Why did America do as well as it did, flawed and troubled and sinful as it was. De Tocqueville characterized America as “a country with the soul of a church.” There is only one way that can happen. Atheism does not do this.
To my observation, the Lord often (though there is no scriptural guarantee, only suggestive patterns of biblical and world history) matches willing evangelists up with the elect. Having the omnipotence of God, He can put whomever He wishes in any time or place. An effort to “awaken the elect” could well succeed.
Get the spiritual foundations right and many other things will go right, not because we were successfully using the spiritual foundations as a tool, but as a witness to the spiritual foundations.
