Jesus Christ changed the world forever. When He was born, He transformed the very way we measure time. He turned aside the river of the ages and lifted the centuries off their hinges. His birthday, His Incarnation, touched and transformed time. Now the whole world counts time as Before Christ (BC) and AD (Anno Domoni - in the year of our Lord). Jesus Christ is the central figure of history. More books have been written about Jesus Christ than any other person in history.
The world before Christ was a world without hospitals, a world without charity, a world without respect for the sanctity of life. Hospitals were an innovation of Christianity. Hence the healing symbol of a cross represents hospitals. The nursing profession was founded by Christians such as Florence Nightingale out of devotion for Christ. One of history’s greatest humanitarian movements, the International Red Cross, was founded by Christians in response to the Scriptural injunctions to care for the sick and the suffering. Christians such as Dr. Louis Pasteur have fuelled some of the greatest practical advances in medicine. Pasteur has probably saved more lives than any other individual in history through his inventions.
