Through St. Faustina, the Merciful Savior has given the aching world new channels for the outpouring of His grace. These new channels include the Image of The Divine Mercy, the Feast of Mercy (Divine Mercy Sunday), the Chaplet, the Novena to The Divine Mercy, and prayer at 3 o’clock in the afternoon, the Hour of Great Mercy.
Although these means of receiving God’s mercy are new in form, they all proclaim the timeless message of God’s merciful love. They also draw us back to the great Sacrament of Mercy, the Holy Eucharist, where the living Lord, who suffered and died on the Cross and whose Heart was pierced with a lance, pours forth His mercy on all mankind, and grants pardon to all who draw near and honor Him. As Jesus told St. Faustina:
My Heart overflows with great mercy for souls, and especially for poor sinners…[I]t is for them that the Blood and Water flowed from My Heart as from a fount overflowing with mercy. For them I dwell in the tabernacle as King of Mercy. (Diary, 367) Read more here.
