Lyric discussion by Crashe 

In the lyrics, "here" is spelled as "hear" multiple times.

The meaning of the song can be summed up in just the title. Heaven is knocking- it is calling on you for salvation and to worship and witness. But all the while, Hell is rising and claiming the world. Basically the theme of the whole song.

I especially like the singer's voice when he's screaming. It sounds like his throat is so dry and he won't be able to scream for much longer. Like he's been screaming for a long time and is reaching the end to where he can't scream any more. Kind of symbolic to the meaning of the song, although I'm sure it wasn't meant that way.
