"Fast & Furious" actor Tyrese Gibson is known to share his Christian faith on social media every chance he gets, and this time, the actor-slash-R&B singer is discussing how God helped him overcome his doubts and fears.

On his Facebook page, Gibson posted a photo with the message: "Don't dig up in doubt what you planted in faith." Then he provided a lengthy explanation why he shared that inspirational message.

"I am posting this for you, are you listening to me? While I'm saying this to you I'm saying it to myself, I'm saying to you. The spirit of doubt is real; the feeling of letting go and walking away is real," he says. "But I'm here to remind [you] of the power and the presence of the Lord Jesus Christ and to tell you that the God I know wants you to learn during those dry spells, he wants you learn how to conquer fears and doubts."

Gibson adds that challenges build character, and if success happens too fast, then people won't be able to appreciate it wholeheartedly. On the other hand, people will truly value things that they've worked hard for.

"I love you and if no one has told you this, I want you to know that I do and your life is worth living. Your projects and visions will materialise. Your kids, nieces and nephews and family love you. If you're like me, finding yourself not being too close to your immediate family and you feel alone sometimes, don't, because as long as you have God in your heart you are never alone," he says.

Gibson concludes his post by asking people to pray for him, and he promised to do the same for his fans.
