The 20th century saw tremendous changes worldwide in politics, economics, science, learning, and ways of living. Democracy, human rights, and civil rights were established in many countries for the first time. Humanity came into modernity. The old ways of living were replaced with the new. Amid such changes, people in the West quietly accepted the decline of the Christian faith as part of the process. But times have changed. In the 21st century, we must decide what we believe, who we are, and what matters to us the most. We must draw a line on the sand which we will not cross. The fiercest spiritual battle for the souls of humanity will be fought in the continent of Europe.
