A website that explains the novena in greater detail is:
Thank you St. Jude for helping me through rough times in my life! It works, if you believe. :)
"May the Sacred Heart of Jesus be Adored, Glorified, Loved & Preserved throughout the world, now & forever. Sacred Heart of Jesus, please pray for me. Saint Jude, Worker of Miracles, please pray for me. Saint Jude, Helper of the Hopeless, please pray for me. Amen."
"O most holy apostle, St. Jude, faithful servant and friend of Jesus, people honor and invoke you universally, as the patron of hopeless cases, of things almost despaired of. Pray for me, for I am so helpless and alone. Please help to bring me visible and speedy assistance. Come to my assistance in this great need that I may receive the consolation and help of heaven in all my necessities, tribulations, and sufferings, particularly (state your request) and that I may praise God with you always."
"I promise, O blessed St. Jude, to be ever mindful of this great favor, to always honor you as my special and powerful patron, and to gratefully encourage devotion to you by publishing this request. Amen."
