Paul has much to say in describing the world in its final days. It will be filled with traitors. Of course, when people are filled with self-love and they have no self-control, then they will do whatever they can to obtain whatever they want. It will matter not who is harmed in the process or what promises and commitments are broken. In previous ages when Christianity exerted a greater impact on society, treason was considered abhorrent. This even by people whose own morals were considered to be questionable. But in our day, we are not surprised when people betray others in order to obtain their own selfish desires.
In the final days, people will be haughty and headstrong. Pride has been the undoing of countless people through the ages. It causes people to be unteachable and closed to the truth that could set them free. Likewise, in those days, people will be lovers of pleasure. Today, it is mind-boggling to calculate the billions of dollars society spends annually on it enjoyment. No expense is considered too great. While we might disdain to spend our hard-earned money on helping the homeless or the oppressed in other countries, we can spend thousands of dollars on our entertainment and feel absolutely justified. What is worse, we love pleasure more than we love God. That might be one of the reasons God commands us to give a portion of our money back to Him. It reminds us that He, and not our happiness, is our first priority.
While it is sobering to read of what people will be like in the end times, it is perhaps even more disturbing to realize how many of those characteristics show up at times in our own life today.
