Since the time of the canonization of St. Faustina, she becomes a permanent theological presence in the reality of the "communion of saints ".
Often, just talking in front of a relic or sometimes by touching a Holy relic, has served to the Saint to intercede immediately with God our Lord to work miracles in the person quickly, reminding you that faith in God is very important, because that faith, is the cord that connects us to God, if there is no faith, there is no contact.
Saint Faustina, You told us that your mission would continue after your death and you would not forget about us (Diary, 281, 1582).
Also Our Lord granted you a great privilege, telling You: “Distribute graces as you want, to whom you want and when you want”(Diary 31).
Relying on this, I ask your intercession for the graces I need, especially
(Here, take a moment to mention your special intention)
Help me especially, to trust in Jesus as you did and thus to glorify His mercy every moment of my life.
Amen.
