"I been through some dark times and it's a lot of people out there in that darkness, in that lost place, in that place where you feel stuck [and] don't know where to begin for the change, where you don't know what to do next," he said in an old video. "God help me... show them the way. Show them the light."
Diddy wrote in the caption that he said the prayer "like a year ago," but thought it was appropriate to share it now that Porter, the mother of his three children, had passed.
"God help us. Love to all," he added.
Diddy's other tributes include a series of Instagram posts and a private memorial service to honor her. In his first public message about her death, Diddy shared that he felt lost without Porter around, comparing the whole ordeal to a "nightmare."
"We were more than best friends, we were more than soulmates," he said on Instagram. "WE WERE ON SOME OTHER SHITT!! And I miss you so much."
Diddy also shared another tribute before Porter's Saturday funeral, thanking fans for their support in a trying time.
"Today we lay to rest our ANGEL. Her spirit lives on with us FOREVER!!!" he wrote. "We thank you all for your prayers and support. You have no idea how much it means to us. We thank GOD for all of you."
Kim Porter was laid to rest in her Georgia hometown a little over a week after she was found dead in her Los Angeles home. Kimora Lee Simmons, Tichina Arnold, and Mary J. Blige were a few of the mourners in attendance.
