We are to be made new in our attitude so that we do not succumb the standards of the world, but live by the standards of God. Our text today says we are no longer to live as the gentiles do, in the futility of their thinking. They are darkened in their understanding and separated from God because of the hardening of their hearts. Now Gentile means the way of life or attitude of one who does not belong to the true God. Worldliness and godliness are opposed to each other.
Worldliness is centered on self.
Godliness is centered on God. Worldliness works for gain. Godliness works for God. Godliness seeks to do the work of God. The attitude of worldliness is darkened in its understanding, separated from the life of God.
