The problems that the world faces - from nuclear proliferation to climate change - can't be tackled by the West alone. They need a coalition of not just West and East but they need a coalition of Christian and Jew and Muslim.
This and this alone is Christianity a universal holiness in every part of life a heavenly wisdom in all our actions not conforming to the spirit and temper of the world but turning all worldly enjoyments into means of piety and devotion to God.
Too many Christians have a commitment of convenience. They'll stay faithful as long as it's safe and doesn't involve risk rejection or criticism. Instead of standing alone in the face of challenge or temptation they check to see which way their friends are going.
