Covenant of works v covenant of grace

Just a quick note in a shameless act of sycophancy to point you to Guy Waters' article inThe Law is Not of Faith, edited by Bryan Estelle, J. V. Fesko and David Van Drunen (P & R, 2009) on the interpretation of Romans 10:5. A fascinating piece worth looking at. His citation of Turretin in the opening pages was itself an eye-opener to me.  Why wasn't I pointed to this 30 years ago? The volume is otherwise a Kline-ian love-fest and at some point we should address some of the issues raised.
