Sara was a holy young women who had begged God to give her a husband. Her prayer, too, was answered when young Tobias asked her to be his wife. In the meantime, Azarias went on to collect the money owed to Tobias. When he got back, he and the couple set of towards home. Young Tobias and Azarias went on ahead toward the end of the trip. What joy there was when young Tobias' worried parents saw him arriving! Next, Azarias told his friend to take the gall of the fish and apply it to his fathers eyes. He did so, and Tobias regained his sight! Meanwhile, Sara, the rich beautiful bride of young Tobias arrived with the servants, cattle, camels, and money which was her dowry. For a whole week everyone celebrated the wonderful happiness that had come to Tobias and his family.
The good man and his son were so grateful to the young man, Azarias, that they did not know how they would ever repay him. When they called him aside to ask him to accept half of all they owned, he revealed a tremendous secret to them: "I am the Angel Raphael," he declared, "one of the seven who stand before the Lord!" Tobias and his were filled with fear and fell to the ground. "Peace be with you, and fear not," Said the Archangel. "For when I was with you, I was there by the will of God." He told them that God was pleased with Tobias because he had prayed, done penance and helped so many people. So He had sent St. Raphael to bring him many blessings. "It is time that I return to God." Raphael concluded, and with that he was taken from their sight and they could see him no more.
To make sure that our prayers are heard by God, we should accompany them, as Tobias did, with little sacrifices and acts of charity toward our neighbor.
