The 31-year-old joked that the clip - which will feature a full children's choir - will save the souls of his fellow bandmates, reports the Daily Star.
“I think after my grandma sees this video, she definitely won’t think we’re going to hell as fast as she did think we were going," he explained.
“Lyrically, the chorus started out being kind of spiritual, but the verses never matched up to it at all."
He added; "Gospel music was a big part of us growing up, so to be able to come back to it is a pretty special thing.”
'Radioactive' will be released on October 11.
