Lucado, Stott, and Piper

From an interview of Max Lucado in the 10/10 issue of CT:

How would you address some critics who suggest your writing is simplistic?

I would give them a good John Stott book or a John Piper book. I realize the I'm kind of nightstand reading. Some people write lullabies; I write lullabies.

I'm fine with Lucado's self-deprecating assessment of his own writing. (He is a uniquely and enormously gifted communicator.) But does John Piper belong in the same sentence as John Stott?

Just asking.
