All grace flows from mercy, and the last hour abounds with mercy for us. Let no one doubt concerning the goodness of God; even if a person’s sins were as dark as night, God’s mercy is stronger than our misery. One thing alone is necessary; that the sinner set ajar the door of his heart, be it ever so little, to let in a ray of God’s merciful grace, and then God will do the rest (Saint Faustina Kowalska, +1937)
