The singer visited St John's Church in Houston, Texas, on Friday, and addressed the gathered survivors of last week's catastrophic hurricane, according to Entertainment Tonight.
Taking the stage at the church, Beyonce said, "This today is a celebration of survival. This church is my home.
"I was maybe nine or 10-years-old the first time I sat there where my daughter is sitting. I sang my first solo here and I just wanna thank you for lifting my family up, for praying for me, and for being such an incredible example of what light and love is."
The 36-year-old singer was joined by her mother Tina Knowles and daughter Blue Ivy, as well as fellow bandmate Michelle Williams.
Earlier in the day, Knowles and Williams helped serve a meal to 400 Harvey survivors.
