According to the Catholic Encyclopedia, "almsgiving," is any material favor done to assist the needy, and prompted by charity. Saint John's heart was filled with compassion for his fellow man. Here is an excerpt from his letter to a friend:
"If we kept before us the mercy of God, we would never be deficient in doing good, while strength was in us. For, when we make over to the poor, out of the love of God, what he himself has given us, his promise is that we shall receive a hundredfold in eternal happiness. That indeed is a fortunate and happy way of gaining a profit! Who will not give over whatever he has to this best of merchants! He administers our business himself, and begs us with outstretched arms to turn to him and weep for our sins, and become servants in love, first for ourselves, and then for our neighbour. For just as water extinguishes a fire, just so does charity blot out our sins. So many people come here that I very often wonder how they can possibly be provided for. But Jesus Christ provides all things and feeds everyone. Many of the poor come into this house of God because the city of Granada is large and very cold, especially now in winter. There are now more than one hundred and ten people living in this house, including the sick, the healthy, the servants and pilgrims. Because the house is open to everyone, it takes in all manner of sick people. There are people with useless limbs, the maimed, the lepers, the dumb, the insane, paralytics, and some who are suffering from cancer. Others are afflicted with senility, and there are many children, as well as the innumerable travellers and pilgrims who arrive here, and whom we provide with fire, salt and water, as well as pots to cook their food. There is no charge made for all this, but Christ is our provider.
So, I am working here in debt, and I am a captive for the sake of Jesus Christ. Often I owe so much that I dare not go out, in case I am seized for my debts. And when I see so many of my brethren in poverty, and my neighbours suffering beyond their strength, and oppressed in mind or body by so many cares, and am unable to help them, it causes me exceeding sorrow."
