The Second Sunday of Easter (April 12) is Divine Mercy Sunday, a day on which our Lord, through the visions He offered to Saint Faustina, promised that the floodgates of His mercy would be open to sinners. This is a wonderful opportunity for the faithful to avail themselves of God's abundant mercy.
The Divine Mercy devotion offers us three steps to follow ... as easy as A-B-C:
        •          Ask for God's mercy.
        •          Be merciful to each other.
        •          Completely trust in God's mercy.
In 2002 Pope Saint John Paul Il granted a plenary indulgence (a remission before God of the temporal punishment for sin the guilt of which is already forgiven") on Divine Mercy Sunday. The indulgence, which follows the "usual conditions (sacramental confession, Eucharistic communion and prayer for the intentions of the Supreme Pontiff)," is granted "to the faithful who, on the Second Sunday of Easter or Divine Mercy Sunday, in any church or chapel, in a spirit that is completely detached from the affection for a sin, even a venial sin, take part in the prayers and devotions held in honor of Divine Mercy, or who, in the presence of the Blessed Sacrament exposed or reserved in the tabernacle, recite the Our Father and the Creed, adding a devout prayer to the merciful Lord Jesus (eg. Merciful Jesus, I trust in you!')."
