On June 10, 1963, John F. Kennedy said: "No problem of human destiny is beyond human beings." A few months later he was dead. I truly think one of the most fundamental problems with humanity is believing that it can really solve its problems apart from God. Please. Let's not kid ourselves. Things can only get worse. Really.
Even within a single nation, the problems confronting the general population are, at best, addressed by stop-gap measures which politicians dream up. Most people, as long as their daily lives remain relatively normal go on about their business until the day they die, seeking not so much permanent solutions to their dozens of problems as mere distractions from them - alcohol, drugs, entertainment, you-name-it. Were this not the case, we would be living in a man-made Utopia, no?
