In today’s world, on which the constant grip of violence and hatred leaves an imprint, man lives in fear and a sense that a dangerous threat is looming. He fears not just the outbreak of a nuclear conflict or a biological disaster. Above all he fears the great variety of manipulation techniques that may be used against himself by another man, who having a vast number of instruments of civilization at his disposal is in a position to limit his freedom, to make it impossible for him to declare his worldview or speak the truth and may even corrupt his conscience by stifling his sensitivity. Protecting himself against all these, he searches unceasingly for an escape from these dangers. At times he takes recourse to the law of interpersonal solidarity, at other times to the values of social justice. However, neither the one nor the other – as life’s experience teaches – can guarantee him a sense of security. Therefore, neither of them can give him the assurance of inner peace. However, there is such a value – demonstrated by St. Faustina Kowalska in the previous century – that is able to heal all his fears and anxiety. It is divine mercy. Humankind will not find peace – she reminds us with the words of Christ spoken to her at one of His revelations – until it turns to My mercy with trust (Diary 300).
