Evangelizing millennials

What is the best way to communicate the Gospel message to the "millennial" generation? Our church has committed itself to reaching out to this group, but I'm concerned about what I perceive as a tendency to "broaden" the Gospel's appeal to twenty-somethings by watering it down and removing all references to sin, repentance, and judgment. To me this seems like a huge mistake. After all, Jonathan Edwards' sermon "Sinners in the Hands of an Angry God" touched off one of the greatest revivals we've ever seen. As I see it, the Church is supposed to be proclaiming the truth, not initiating a "dialogue" about it. Can you help me sort this out?
