New Calvinist Tricks for Old Calvinist Dogs

I earlier wrote a couple of posts on the attitude that Old Calvinist types like me should take towards the New Calvinism movement.  The first post argued that Old Calvinists should be generally grateful for the New Calvinism, while the second post argued that Old Calvinists should resist jumping on the New Calvinist bandwagon.  Today I want to point out that while Old School observers will have a number of reservations about the newer movement, we should be willing to learn from it as well, receiving all the benefit that God seems to intend for the faithful Old Calvinists dogs who still need to learn a few new tricks. I would suggest at least three ways in which Old Calvinists should be willing to benefit positively from the interests, examples, and criticisms of the New.  

First, the New Calvinism can show Old Calvinists some topics to which we have given too little attention and emphasis.  An example can be seen in the John Piper address given at Westminster Seminary.  In my view, his most valuable remarks came toward the end when Piper noted the ecclesiological implications of Reformed soteriology.  Piper rightly stated that "racial and ethnic diversity is not overly addressed in our churches and is central to the aim of the blood work of Christ in ransoming a people for God and a bride for himself."  He pointed out that the Reformed doctrine of total depravity ought to eradicate all racist thinking, since we see ourselves humbly united in the condemnation of sin and our great need of grace.  Likewise, he points out that unconditional election severs the very root of racism, since it is free grace and not any human distinction that grounds our salvation.  I give this as a potent example of how New Calvinists are saying things that are good, true, and important, and which Old Calvinism has relatively neglected.
