'The critical question'

From John Piper in his book God Is the Gospel (thanks to Justin Taylor):

The critical question for our generation — and for every generation — is this:

If you could have heaven, with no sickness, and with all the friends you ever had on earth, and all the food you ever liked, and all the leisure activities you ever enjoyed, and all the natural beauties you ever saw, all the physical pleasures you ever tasted, and no human conflict or any natural disasters, could you be satisfied with heaven, if Christ were not there?

And the question for Christian leaders is: Do we preach and teach and lead in such a way that people are prepared to hear that question and answer with a resounding No?
