The US athlete leaped to a season's best 17.86m in the triple jump beating fellow American Will Claye into Silver.
Speaking before the Games to Premier's media partner Passion for Sport about his faith, he said: "This is what I do it for.
"It's what keeps me grounded. It's what keeps me motivated.
"My grandmother got a cell phone for Christmas and she texts me inspirational verses. She always says give God the glory and that's what I do."
After qualifying for the final at Rio he put a message on Twitter stating the power of prayer is unbelievable.
The power of prayer is unbelievable! Thank you for all your well wishes and support. I truly felt it. #Rio2016 #triplejump #blessed
