A lack of a comprehensive biblical worldview has left Christians open to a blind-side attack from humanists who have developed a comprehensive secular worldview. The adjective secular comes from the Latin saeculum, which means “time” or “age.” “To call someone secular means he is completely time-bound, totally a child of his age, a creature of history, with no vision of eternity. Unable to see anything in the perspective of eternity, he cannot believe God exists or acts in human affairs.”
