Very often people think that working miracles is an art, a skill... may be!! But I believe it isn't. In this light, as I read the life of St Francis de Sales (abridged version of Fr Lens' A Drop of Honey) I came across this statement of this saint: These people think I can work miracles; all that I do is pray.
More than 'doing' something, miracles are mostly by-products of prayer and deeds - genuine and altruistic. No wonder during the beatification process of St Francis de Sales, Pope Alexander VII stated: We have here more miracles than are required to beatify 50 other Servants of God.
