“But what are you to do if when you share with your neighbor you yourself are left without something you need? What but ask in full faith (Acts 4:29; 28:31) from him who gives generously to everyone and does not grudge (Jas 1:5), who opens his hand and pours blessing on every creature (Ps 144:16), there is no doubt that he will come to your aid generously when you are in need, since he is so generous in time of plenty. Scripture says, “First seek the Kingdom of God and his justice and all these things will be added to you” (Mt 6:33; Lk 12:31). He promises without being asked to give what is needed to him who is not greedy for himself and loves his neighbor.”
