The "Shazam!" actor, 42, took to Twitter on Monday to respond to a fan who had asked where he was to answer he was at his dad's side in a hospital room.

"Death does not sadden or frighten me," he wrote. "It's actually an incredibly powerful part of life. One that we'll all reach one day. Where we get to go back to God, the source, and be surrounded by the highest vibration of energy, love."
In a separate tweet, the "Chuck" alum asked fans to send prayers for his family -- especially his dad.
"But for anyone out there that feels like rollin up some spiritual sleeves and prayin, send some up for my pops," he tweeted. "Pray that he be as comfy and at peace as a man could get. And that he head home with no fear or regrets, knowing how loved he is."
Levi's tweets drew support from fans as well as "The Vampire Diaries" co-creator Julie Plec, talk show host Sherri Shepherd, "Glee" favorite Jane Lynch and more.
