To me this song is about waiting for death. It was put directly at the end of "Waste of Paint" because that song has him desiring to "believe in (his) soul" or God and this one is about a situation where an angel falls on the earth and he is shown that God exists. Conor wants this to happen so he'll know that there's a meaning or truth to this life and although he doesn't expect it, he's still desiring to die so he can find out and get free. He basically is saying that religion is not enough to prove God and it's gonna take death (a good thing) to make sure.
