Taking this in a non-religious context (not saying i don't see the religious aspect either) I think this song is just about how no one ever seems to say anything about the happy things that happen in life, spending all their time complaining. When bad things do come along, we should draw on our happy experiences to help us get through it, and 'wake up' and remember that things will get better, as well as the fact we're never alone (again linking to the religious aspect)
