My mother many years ago educated me about St. Jude. Like many I thought she meant St. Judas. After I got out of the Army, I felt lost and desperate for a path forward. I prayed my novenas to St. Jude and my prayers were answered.
I have prayed to St. Jude over the years asking for intercession for others and thanking him for his help those 50 + years ago. Presently. I seek his help for my children, friends and family members and to those I don't know but feel they could use his help.
