Miracle of Holy Fire - one of the gratest miracle of God

The miracle is not confined to what actually happens inside the little tomb, where the Patriarch prays. What may be even more significant, is that the blue light is reported to appear and be active outside the tomb. Every year many believers claim that this miraculous light ignites candles, which they hold in their hands, of its own initiative. All in the church wait with candles in the hope that they may ignite spontaneously. OOften unlit oil lamps catch light by themselves before the eyes of the pilgrims. The blue flame is seen to move in different places in the Church. A number of signed testimonies by pilgrims, whose candles lit spontaneously, attest to the validity of these ignitions. The person who experiences the miracle from close up by having the fire on the candle or seeing the blue light usually leaves Jerusalem changed, and for everyone having attended the ceremony, there is always a "before and after" the miracle of the Holy Fire in Jerusalem.
