One day a brother said to blessed Francis: “Father, your life and manner of living were and are a light and a mirror not only for your brothers but also for the entire Church of God, and your death will be the same. Although for the brothers and many others your death will mean great grief and sorrow, for you it will rather be a great consolation and infinite joy. You will pass from great toil to the greatest rest, from many sorrows and temptations to infinite happiness, from your great poverty, which you always loved and carried from the beginning of your conversion till the day of your death, to the greatest, true, and infinite riches, from death in time to life in eternity. There you will forever behold face to face the Lord your God whom you have contemplated in this world with so much desire and love.”
After saying these things, he said to him openly: “Father, you should know the truth: unless the Lord sends his own remedy from heaven to your body, your sickness is incurable and, as the doctors already said, you do not have long to live. I told you this to comfort your spirit, that you may always rejoice in the Lord, inside and out; especially so that your brothers and others who come to visit you may find you rejoicing in the Lord, since they know and believe that you will die soon. Thus, as they see this and, after your death, others hear about it, your death, like your life and manner of living, may be held in remembrance by all.”
Although racked with sickness, blessed Francis praised God with great fervor of spirit and joy of body and soul, and told him: “If I am to die soon, call Brother Angelo and Brother Leo that they may sing to me about Sister Death.”
Those brothers came to him and, with many tears, sang the Canticle of Brother Sun and the other creatures of the Lord, which the Saint himself had composed in his illness for the praise of the Lord and the consolation of his own soul and that of others. Before the last stanza he added one about Sister Death:
"Praised be You, my Lord, through our Sister Bodily Death, from whom no one living can escape. Woe to those who die in mortal sin. Blessed are those whom death will find in Your most holy will, for the second death shall do them no harm."
