St. Jude — the "Worker of Miracles" and "Patron of Hopeless Causes" — is invoked in desperate situations. Yet in his New Testament letter, he exhorts the faithful to persevere despite adversity. He writes: But you, beloved, build yourselves up in your most holy faith; pray in the Holy Spirit. Keep yourselves in the love of God and wait for the mercy of our Lord Jesus Christ that leads to eternal life (Jude 20, 21). According to one popular story, St. Jude was entrusted with an image of Jesus. He delivered it to a king of Edessa, who was suffering from leprosy. The king was cured, and the king and his people became Christians. For this reason, the saint is usually portrayed with an image of Jesus as a medallion on his chest, as well as a tongue of fire, indicating his receiving the Holy Spirit at Pentecost.
