It is traditional to publish or share a devotional image or prayer to Saint Jude after a favor is received, as a sign of gratitude. Many also place a novena candle or prayer card in their home as a reminder of their trust in his intercession.
"Most holy apostle, Saint Jude, faithful servant and friend of Jesus Christ, I come to you and beg for your powerful intercession. Assist me in my present and urgent need. May I receive the comfort and help I need to bring me to the presence of God. I promise to be a faithful devotee and to honor you as my special protector and advocate. Amen." prayer to saint jude for impossible situations
