I understand that Christ is referring to ultimate freedom from sin, death and the grave here in John 8. However, I believe there's an application of this truth to political liberty. I ran across this John Adams' quote this morning. I don't know if he was a Christian or not, but he clearly understood a "few things." The man was brilliant. Here's the quote:
While our country remains untainted with the principles and manners which are now producing desolation in so many parts of the world; while she continues sincere, and incapable of insidious and impious policy, we shall have the strongest reason to rejoice in the local destination assigned us by Providence. But should the people of America once become capable of that deep simulation towards one another, and towards foreign nations, which assumes the language of justice and moderation, while it is practising iniquity and extravagance, and displays in the most captivating manner the charming pictures of candour, frankness, and sincerity, while it is rioting in rapine and insolence, this country will be the most miserable habitation in the world. Because we have no government, armed with power, capable of contending with human passions, unbridled by morality and religion. Avarice, ambition, revenge and licentiousness would break the strongest cords of our Constitution, as a whale goes through a net. Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other.
My takeaways from this are 1.) it is only through holding onto a high (biblical) moral standard that we can enjoy the fullest extent of liberty; 2.) if we can't self-govern ourselves by God's law and grace, we are destined to be ruled by some form of tyrant. This is reality and this is what the United States of America needs to understand if it is to continue with the original intent of the Founding Fathers.
The wise of heart will receive commandments, but a babbling fool will come to ruin. (Proverbs 10:8 ESV)
