Tyrese Gibson is really struggling to cope with the death of his close friend and "Fast & Furious" co-star Paul Walker.

After an emotional visit Sunday to the crash site where Walker died, Gibson, 34, posted an " open letter to God" on his Facebook page Monday.

"Father God I love you, I trust you," he wrote. "I will do what you tell me to do … Order my footsteps and I will walk."

He continued, "My heart is hurting badly but in this darkness you used me as a light with my brothers family tonight ….. Use me up father God I owe you."

Paul Walker's father told KABC that Gibson was instrumental in helping the family grieve and couldn't say enough nice things about the singer/actor.

Gibson took to Facebook again on Tuesday to voice his pain after he said he'd spoken to Bishop TD Jakes about healing and closure.

"Then I went online and came across this powerful word he spoke at a recent funeral and the word was 'I know it feels like death has won,'" he posted.

Gibson added, "BISHOP TD JAKES: In moments like this, it feels - it feels like death has won. But the bible says that love is stronger than death … You look around and everybody you love and everybody you can count on and everybody you can trust seems to be slipping through your fingers."

Continuing to infuse his own words to the TD Jakes sermon, Gibson said, "Don't you dare think that death has won."

"You'll be driving down the street one day and you'll hear Pauls voice talking in your head," Gibson said. "Something he said or something he did will pop up in your spirit and you'll giggle inside of yourself as if he were sitting in the car with you."

More than 1 million people have "liked" this post, with more than 40,000 comments supporting Gibson.

Gibson has also been very vocal on Instagram. He was shaken the night of Walker's death, saying "I just don't understand, My heart hurts it's broken."

On Tuesday, he posted a touching video of the two on the red carpet, Tyrese telling Walker "I just love you man."
