I'm glad I've given up drugs and alcohol. It would be awful to be like Keith Richards. He's pathetic. It's like a monkey with arthritis, trying to go onstage and look young.

Drugs are a bet with your mind.

I have tried drugs and a little of everything else, and there is nothing in the world more soul-satisfying than having the kingdom of God building inside you and growing.

The thing about drugs and sex is that you lose all your inhibitions. I've had sex in trains, planes, wine bars... and quite a few car parks!

When people go to rehab and come out, they go through a difficult period, a lot of people. I never had that. I was so glad to be rid of all that crap that for me, to learn again and to function as a human being and learn how to participate in the human race again was just pure joy.

Once you've seen a solution to the disease that's tearing you apart, relapsing is never fun.
