I think I was always an old soul, even as a teenager.

Now that I have seen I am responsible, faith without deeds is dead.

In the end, no matter how my records are panned or praised, if there are kids and communities in developing nations that have improved living conditions and are finally getting access to things we all have a basic right to (clean water, education, healthcare) because I am able to advocate, raise awareness or funds in some small way, then my life has achieved something that in the end means far more than having the track or album of the moment.

David Bowie is the quintessential English gentleman and, of course, a musical and generational institution. I only played support for him for one night (not a whole tour) but he was incredibly gracious and generous toward me and I've certainly never forgotten it.

Then Jesus introduced Himself to me. Though my birth certificate reads 1983, I reckon I was born in 1999, when I met Jesus - not in a church or on a camp or through people, but alone in my bedroom with an open Bible and a tangible revelation that the Son of God was not only real, but alive and awesome and stronger than the chains that bound me.

The writing and making of each of my albums has been such a different beast each time, so I'm interested in seeing what kind of animal the fourth one turns out to be!

Obviously, it was a big life change for me and quite a shock to suddenly have these songs I'd written in my bedroom as a far-too-intense teenager all over the airwaves and see my face on buses, especially in a small country like New Zealand, but at the same time it was such a thrill and an honour knowing that my music was reaching people.
