O most holy apostle, Saint Jude, faithful servant and friend of Jesus, the Church honours and invokes thee universally, as the patron of hopeless cases, and of things almost despaired of. Pray for me, who am so miserable. Make use, I implore thee, of that particular privilege accorded to thee, to bring visible and speedy help where help was almost despaired of. Come to mine assistance in this great need, that I may receive the consolation and succor of Heaven in all my necessities, tribulations, and sufferings, particularly (here make your request) and that I may praise God with thee and all the elect throughout eternity. I promise thee, O blessed Jude, to be ever mindful of this great favour, to always honour thee as my special and powerful patron, and to gratefully encourage devotion to thee. Amen.
(St Jude is the patron saint of lost causes. When things seem hopeless and helpless, then this prayer has worked miracles for all who've turned to St. Jude in times of need.)
