Evangelist, Chris White, spoke after the pop star took to the stage during the half term show of the American football championship game in Minnaepolis on Sunday night.
The United Evangelical Church minister and retired teacher told the Christian Post: "To me, the most moving part of her performance was when she sang her new song, 'Million Reasons'.
Released last year, 'Million Reasons includes the lyrics: "I bow down to pray. I try to make the worst seem better. Lord, show me the way.
"To cut through all his worn out leather. I've got a hundred million reasons to walk away. But baby, I just need one good one to stay."
Chris White said Lady Gaga, whose birth name is Stefani Germanotta, attended his classes at the Convent of the Sacred Heart in New York, where he taught mathematics between 1995 and 2007.
Describing Lady Gaga as a "bright and talented student", he said he felt prompted to prayer for her ever since he met her for the first time.
"I don't believe that the Lord put her in my classes by accident, but for the sake of His own purposes in her life.
"Lady Gaga, like many famous people, is bleeding on the inside because fame and success can never satisfy the human heart.
"I have been praying for her now for years, that the Lord will indeed one day show her the way to 'cut through all the worn out leather' of this dying world."
Meanwhile, posting on Twitter after her Super Bowl half time performance, Lady Gaga said: "So"!!!!!??? What did you guys think of the #PepsiHalftime show? I love performing for you."
