I see your point, but I don't entirely agree. Let me see if I can explain why.

I know it is fashionable to use "illustrations", but some of these seem to be the whole sermon.
Let me start by laying out my biases. I am a "storytelling" preacher. I preach using illustrations and stories.
I don't do this to be "fashionable" (although I do agree that there are probably pastors out there that do). I preach this way primarily because that is my God-given design. That is how God made me. I think that God made me this way because those that He has called me to minister to need this type of interaction. These are people that have been alienated by the "traditional" church service.
Don't get me wrong -- I don't disregard the use of scripture. I preach based on topics that the Spirit has laid on my heart. I then use scripture to support the points that God has given me to make. I fully believe that the Word is a living, breathing document, and is powerful in use.
I believe that God desires that different people spread the same message in different ways. I've heard it explained this way: say we decide to attend a party in LA and we are leaving from my home in Atlanta. We agree to invite everyone that we come in contact with on our journey to come to this party with us. Our goal is the same. However, you decide that the best route for you to take in your sports car is to travel along the interstates. At every rest area, at every restaraunt, at every gas station that you stop at, you invite all those people. I decide that the best route for me to go in my pick-up truck is to travel the backroads -- again inviting everyone that I come in contact with to the party. Macrina decides that she should travel via airplane, inviting eveyone on the plane and in the airports on layovers to the party.
When we get to LA, there will be many more people there than if we had all traveled the same road. You will see people that me and Macrina will never see, and vice versa. So the goal is the same, but many more people will hear of the news because we traveled different roads.
It's the same with the Kingdom. Our goal is the same -- how we get there depends on how God made us. We each travel along the path that God has laid out for us, so that we can invite many more people to the party that is the Kingdom of God.
I guess what I'm saying in a roundabout way is that what works for you may not work for me -- and what works for me may not work for Macrina, or others. But it what God wants me to do to further the Kingdom.
Please don't take this as a slight to those that preach expository messages. I hope that I have made myself clear that we need preachers who are willing to preach using his or her God-given design -- and if God designed you to preach expository sermons, then there are people that need that that God wants you to minister to.
I will agree, however, that sometimes we do try to reduce the symbols of our beliefs too much to try to make non-believers comfortable. We remove the crosses from our worship gatherings, we reduce the role of scripture in the service. We don't need to do that. Non-believers expect to see those things. Most non-beleivers are very spiritual people -- they just haven't accepted the freely offered gift yet. They expect to see the cross -- they expect to see scripture from the Bible used. We should, and must, use these things.
