The world…is characterized by the subtle and relentless pressure it brings to bear upon us to conform to its values and practices. It creeps up on us little by little. What was once unthinkable becomes thinkable, then doable, and finally acceptable to society at large. Sin becomes respectable, and so Christians are no more than five to ten years behind the world in embracing most sinful practices.
