The United States Constitution was created in 1787. The Quran? Between 609-632. The earliest writings of the Bible were written nearly 3,500 years ago. These documents and texts (and many like them) define the way a lot of us live today. They give us law, order, purpose, and direction. There's only one problem: they're outdated.
The priceless, holy, supreme documents we use as guidelines for our lives rarely change (e.g. the last update to the United States Constitution happened 24 years ago). On the other hand, people change all the time. We grow, evolve, and become more complex year after year. The fact that, in 2016, we're living our lives based on documents created hundreds and thousands of years ago is a great paradox. It's the reason we have a hard time conquering issues like marriage equality, gun violence, religious extremism, draconian laws, and more.
The documents we look to for guidance weren't created for the future; they were created for the way things were at the time. They're not meant to be evergreen, and they don't take into account unforeseen circumstances that will continue to shape our lives. This is one of the most significant issues among the human species. We can't fully grow when we're held back by laws and values of the past. Either we take it upon ourselves to update and overhaul these documents, or we'll continue to fight the same societal battles over and over again.
