This is a quote from Mark Driscoll posted over at John Piper's blog (emphasis is Piper's):
The curious paradox of the atoning death of a bloody Jesus rising above the plane of human history with a mocking crown of thorns is that he is offensive in an attractive way. It is the utter horror of the cross that cuts through the chatter, noise, and nonsense of our day to rivet our attention, shut our mouths, and compel us to listen to an impassioned dying man who is crying out for the forgiveness of our sins and to ask why he suffered. Tragically, if we lose the offense of the cross, we also lose the attraction of the cross so that no one is compelled to look at Jesus. Therefore, Jesus does not need a marketing firm or a makeover as much as a prophet to preach the horror of the cross unashamedly.
