"Undying" by Demon Hunter-What's with the empty casket?

Demon Hunter's "Undying" video is about where the members in the group will go after death. Demon Hunter is a Christian band, so they share their Christian perspective. The video opens with people assembling in a church for a funeral. As this is occurring, Demon Hunter sings about the choice they have made in their life about where they want to be after death. They each want more than just becoming part of the soil ("Cause when I made the choice to live beyond the dirt we tread/ I felt the curse of mortal limit fall before it was said.") As the video continues onto the chorus, it shows each individual that is attending the funeral service singing the chorus. The chorus explains how death will hurt some emotionally, but ultimately, it is a glorious thing for those who believe in Jesus Christ. The individuals singing are those who have "One final heart-break." However, the man who died is a believer in Jesus Christ, and therefore is going to heaven, as heard in the chorus when Demon Hunter sings, "...And blinding lights will guide our way/ free us our blind state/ they will call us by our name/ undying." During the chorus, images of stained glass windows that are pictures of angels show, signifying that the angels will come to guide the dead to heaven. The funeral continues as Demon Hunter witnesses about their faith. They explain how it is only through Jesus Christ that one can go to heaven. They relate to Jesus dying on the cross for our sins by saying, "No one can take away the blood that covers over my fall." They explain how only through believing in Jesus that one can go to heaven, as seen in the second verse; "Tearing through these days I find/ the tolerance to strive and push on/ I know what lies beyond this life for me is already won/ no one can take away the blood that covers over my fall/ without the blood of perfect life/ I know I'm nothing at all/ so now I reign forever hallowed in eternity's hand/ no man can shake me from the everlasting ground I stand." The chorus then comes, and the lead singer of Demon Hunter, Ryan Clark, steps out of a car, which could possibly be a Hurst. As he walks into the church, the people are frightened and run away because he is suppose to be the one in the casket. When he walks up to the casket, it is empty, showing that he has continued on the heaven. Each member of the band remains in the church, while they sing the bridge about being the ones who will go on to heaven. Those who ran out of the church represent non-believers who fear what may come of them after death. The term "Undying" refers to those who will continue on to heaven, which are followers of Christ.
