'The fundamental questions every sermon should address are these two questions:
- "Why do we have trouble living right?" Answer: Because in some way we don't really believe the gospel, or rest and rejoice in who Jesus is and what he did for us.
- Why should we live this particular way?" Answer: Because Jesus lived this way for us at infinite cost, and this removes our need to live in any other way.'
Timothy Keller, Our New Global Culture: Ministry in Urban Centers, p.10.
