According to Oxford Dictionary, the word 'miracle' is defined as the following:Lourdes (a town in South West France) is believed to be a place where miracles can happen. It started from 150 years ago when a 14 year old girl claimed to see the Virgin Mary. According to the Catholic church, after visiting Lourdes people have actually been miraculously healed. There are over 5 million visitors each year, so far the miracle healing only happened to 67 people. Guess it depends how strongly you believe and how deep your faith is. God exists only when you believe in him.
