O Blood and Water, which gushed forth from the Heart of Jesus as a fount of Mercy for us, I trust in You. (187)

You Yourself, Jesus, surely out of love for us, underwent such a terrible Passion. Your Father's justice would have been propitiated with a single sigh from You, and all Your self abasement is solely the work of Your mercy and Your inconceivable love ...At the end of Your death on the Cross, You bestowed upon us eternal life; allowing Your most holy side to be opened, You opened an inexhaustible spring of mercy for us, giving us Your dearest possession, the Blood and Water from Your Heart. Such is the omnipotence of Your mercy. From it all grace flows to us. (1747)

You expired, Jesus, but the source of life gushed forth for souls and the ocean of mercy opened up for the whole world. O Fount of Life, unfathomable Divine Mercy, envelop the whole world and empty Yourself out Upon us. (1319)
