In his May 5, 2004 sermon at Clearwater Christian College, Kevin Bauder had this to say about the way in which we gain a hearing for the gospel:

We never really gain a legitimate hearing for the gospel by making ourselves impressive, because the gospel really isn’t about us. And by showing people how impressive we are, far from gaining a hearing for the gospel, we are distracting peoples’ attention away from the gospel.

Instead, he argues, we should show people Christ, and make him impressive, by modeling our lives after him, i.e., that we should think like he thought. His sermon text is Philippians 2.

Clearwater has posted several of the sermons Bauder has preached there. Here are links and summaries for all of them:

I would also like to highlight some sermons by Dr. Robert Delnay preached at Clearwater.
