[The “world” is the system] which men are in basic agreement about what is right and wrong, valuable and worthless, important and unimportant. Sinful men have many different ideas and standards, but they are in total agreement that the network of things in this world is more important than the divine perspective of God. In this most basic world outlook they are of one mind. They resolutely work to fulfill the goals and values of their system, though it defies God and always self-destructs. Sinners are persistent in their rejection, and the worse their system becomes, the more they try to justify it and condemn those who speak the Word of God against it.
