I guess it shows we need both Law and Grace, otherwise we wind up with a weak Gospel that doesn't do much of anything because there is not much people need to be saved from (but we feel good about ourselves because we are "nice" people and that is all that matters). It is interesting that this is man's attempt to make the Gospel stronger but instead it waters down the Gospel. It is ironic that while Lutheranism has a sound answer to the Law vs. Grace dilema, some people want to "improve" Lutheranism and copy the mistakes others have made.
BINGO!
Lutherans theological gift to Christendom is the careful balance (akin to Tevye fiddling on the roof) between Law and Gospel...and the similar tension of being a justified sinner.
The gift is irreparably broken when fed through the gristmill of Hegelian synthesis.
