The lead singer and one other member of the band are actually Mormons (or members of The Church of Jesus Christ of Latter Day Saints), and I'm also a member of that church and love it to pieces and also just got back from serving a mission for 2 years in Canada teaching people about the church but I just love the church so much and love imagine dragons so much as well. My sister's friend actually grew up with them in Utah and she said that at the time this song was written the lead singer's brother was on a mission in Africa and his brother wasn't actually allowed to listen to outside music but he still wrote this song for his brother. Missionaries start serving when they are 19 years old so that's why he mentioned he's just a man on a mission and also that he took a photo of himself when he was only 19. That's why there are also words about redemption, and why he wants no trouble. And the lyrics are actually "pray" for me brother, not "break". The church is so awesome and if anyone wants to learn more they can totally ask me questions because I love it so much.
