I recently heard Mike Reeves speak about how as reformed folk we have majored on justification by faith but have neglected the end to which this points—union and delight in Christ. Here is the snippet of video beginning at the 27:20 mark of Reeves answering the question:

I also found a talk he does further on this matter here.
