Jesus Came To My Birthday Party

From an interview in Drum Media:

On people's surprise at lead single Jesus Came to My Birthday Part having overt Christian overtones: 'We don't really care- I mean that's a pretty silly song. I think probably one of the best things about producing music is that people can think what they want about it- they can make good interpretations and they can make bad interpretations- so it doesn't really matter to me. I guess that's a part of our lives, and when you're writing songs it sometimes just comes out in one way or another. As far as I'm concerned it's not that big a deal.'

I have an overwhelming feeling when i try to relate to this song. I grew up in a Christian home and when I moved away after 18 I began to lose touch with Christ and God and such. It was not until a bit later that I began to seek a goodness which Jesus personifies and I found that in the people I met day to day. I returned to sort of faith in Christ that felt different than when I was a kid. That joy a child feels at their birthday party began to return in little moments with down to earth people that know what's important: love.

I think the repetition of the chorus is trying to put us in that childlike joy and feeling of being loved.
