Tyrese Gibson still struggling with Paul Walker's death; sends "Open Letter to God"

Tyrese Gibson is still trying to overcome the loss of his friend and costar, Paul Walker. Like many family members and fans, Gibson is still struggling with the untimely death of Paul Walker, who was  killed in a car crash on Saturday.

According to PEOPLE, Gibson posted a heartfelt message to his Facebook account on Tuesday, mourning his Fast and Furious costar.

"In moments like this, it feels - it feels like death has won. But the Bible says that love is stronger than death," Gibson also paraphrased a funeral sermon by Bishop T.D. Jakes.

"Your tears may flow. Your pain may come," Gibson continued. "You'll be driving down the street one day and you'll hear Paul's voice talking in your head. 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. And you will find that people that you really love, they may leave you outwardly, but they never leave you inwardly."

PEOPLE also said, Gibson created a Facebook post entitled, "My open letter to God ... " on Monday.

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

Our hearts go out to the family, friends, costars, and fans of Paul Walker.
