I write music to glorify Christ Jesus - this must be my main aim; it is an imperative (okay i've been reading too much of Kant).

But why? Because we were created to give Him glory.

So

"Still madly in love" is for Jesus Christ and His Glory

"Autumn" is for Jesus Christ and His Glory

So are all the other songs. All the songs.

The Westminster confession is right; we are created for the glory of GOD and our aim is to give Him glory.
