Divine Mercy

"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 want to punish aching mankind, but I desire to heal it, pressing it to My Merciful Heart. I use punishment when they themselves force Me to do so; My hand is reluctant to take hold of the sword of justice. Before the Day of Justice I am sending the Day of Mercy."
