This double rainbow appeared on the feast of Divine Mercy 2012 at a Divine Mercy shrine in the Philippines. The statue is 50 feet tall and the rays are staircases into the heart where the is a chapel with Eucharistic adoration.
Saint Maria Faustina Kowalska is a Catholic mystic, prophetess and nun who lived in Poland between 1905 and 1938. God’s mission for her was that she was to proclaim the messages and visions she received from God to the whole world. The messages are all about God’s mercy. He is calling souls to trust in Him. The two necessary miracles required for her canonization were met. Both were miraculous healings. You can read about them here:
Her diary has sold over 800,000 copies worldwide. She is one of the greatest saints of the Catholic Church. These are some of the messages from her diary.
“In the Old Covenant I sent prophets wielding thunderbolts to My people. Today I am sending you with My mercy to the people of the whole world. I do not wish to punish aching mankind but I desire to heal it, pressing it close to my merciful heart. My hand is reluctant to take the sword of justice. Before I come as a just judge I am coming as the merciful savior.” (Diary 1588)
Jesus told Saint Faustina in the diary “Let no sinner be afraid to approach me.” He said of those who trust in the mercy of God, “I shall protect them Myself at the hour of death, as My own glory. And even if the sins of the soul are as dark as night, when the sinner turns to My mercy, he renders Me the greatest praise, and becomes the glory of My Passion. When a soul praises My goodness, Satan trembles before it and flees to the very bottom of hell” (Diary, 378).
