Justification and sanctification are both God's work, and while they can and must be distinguished, the Bible won't let us separate them. Both are gifts of our union with Christ, and within this double-blessing, justification is the root of sanctification and sanctification is the fruit of justification.
I like to separate the music- and lyric-writing processes if I can. I'll sort of noodle around on my keyboard and my computer until I have a beat or a chord progression, I'll record it as a loop, export it to iTunes, then walk around with the loop and sort of talk to myself in the loop, and that's how I get the lyrics.
I'm interested in creating a little sound world for songs, really crafting it, building it, and making it like a little doll's house with little things inside it, staircases and rooms and everything kind of relates to everything else. I've never seen it as drums, bass, guitar and vocals in very separate spaces.
