The country doesn't have to fall apart, but if past practice is any indication, we're in for an awful lot of hard times until we develop a new perspective.
Since we have been established as a nation by contract with Almighty God, so long as we honor that contract, we have a Divine right to exist as a nation. When we breach that contract for any indulgence rather than shoulder the responsibility of maintaining it, then not only do we have no Divine right to exist as a nation, it therefore becomes God's responsibility to send enough judgement our way that we may come to repentence, as a nation, and once again honor the contract to experience God's blessings.
The last time we breached the contract, we simply re-defined one simple term: "liberty". We expanded the definition to include "slavery", though not for everyone; just a segment of a minority group.
Meanwhile God, true to His nature, allowed us to address the issue in our governmental system, which we did after nearly a hundred years. In a U.S. Supreme Court decision, (the Dred Scott case) we in effect said: "We will have slavery." And since congress didn't override the decision, which they have the responsibility to do, it became God's responsibility by default. He was equal to the challenge, and brought enough judgement on us as a nation that we finally did address the issue at the national level thereby reestablishing the Devine contract that allowed us to become a nation while at the same time allowing us to once again receive His blessings.
Though the issue died slowly, equality by law was addressed at the national level with the passage of the civil rights laws.
Then in just a very few short years, we did it again when New York in 1972 legalised abortion by expanding the term "life" to include "abortion" though not for everyone, just a segment of a minority group. God, true to His nature, allowed us to address the issue through our courts. The U.S. Supreme court said in effect, "We will have abortion." And since congress doesn't override their decision, we will have judgement. We'll need enough of it to either develop a new perspective as a nation by addressing the original contract that established us as a nation, or we perish as a nation.
It was a very simple contract, only calling for the protection of three elements: The right to life, liberty, and the persuit of happiness. Without the Devine contract of the Declaration of Indipendence, the Bill of Rights and the whole of the Constitution mean nothing.
When we make the mistake of thinking that this is "our" country, I imagine God saying to Himself, "Don't they know its "OUR" country?"
