By Rodney Pelletier, Church Militant - In a time where evil and darkness are immense, God's grace and mercy are all the more available to sinners. Besides frequent, devout and prayerful reception of the sacraments of confession and the Holy Eucharist, devotion to the "Three Hearts" is a way for people to achieve great holiness... Devotion to the Sacred Heart of Jesus has existed since the beginning of the Church. But it was invigorated when Our Lord appeared to St. Margaret Mary Alacoque in France, starting in 1673.
