"Bryce and I had the tremendous pleasure of spending some time with our new buddy Elle and a few other patients at Great Ormond Street Children's Hospital in London," the 37-year-old actor wrote on his Instagram post. "I'll never fail to be moved by the unbreakable spirit of a child. #godisgood Psalm 107:8-9"

"Huge shout out to the loving staff at the Great Ormond Street Children's Hospital," Pratt added in a second post. "Thank you for all that you do!!! #angels"

The hospital visit comes a week after the actor announced that he's auctioning off a visit to the set of the Jurassic World sequel to raise money for the orthopedic center at Seattle Children's Hospital. The Guardians of the Galaxy star and his wife, Anna Faris, spent a lot of time in the hospital's neonatal, intensive care unit when their son, Jack, was born prematurely in 2012.

"You can do a big premiere. You get your star on the Walk of Fame. You can do all those things and none of them make me feel anything remotely close to what it feels like to go to Seattle Children’s Hospital and be with these kids and their families," he said in an interview with Yahoo Style about giving back.
