The quote below is by  Scottish Presbyterian Thomas Chalmers (1780–1847), who  is speaking specifically of the English Particular (Calvinist) Baptists would held to the LBC-1689. He states the following from his observations of them during his time,

Let it never be forgotten of the Particular Baptists of England that they form the denomination of [Andrew] Fuller and [William] Carey and [John] Ryland [Jr.] and [Robert Hall [Jr.] and [John] Foster; that they have originated among the greatest of all missionary enterprises; that they have enriched the Christian literature of our country with authorship of the most exalted piety as well as of the first talent and the first eloquence; that they have waged a very noble and successful war with the hydra of Antinomianism; that perhaps there is not a more intellectual community of ministers in our island or who have put forth to their number a greater amount of mental power and mental activity in the defence and illustration of our common faith; and, what is better than all the triumph of genius or understanding, who, by their zeal and fidelity and pastoral labour among the congregations which they have reared, have done more to swell the lists of genuine discipleship in the walks of private society—and thus both to uphold and to extend the living Christianity of our nation.

From Presbyterian Thomas Chalmers personal experience and witness of the Particular Baptist during his time, they defended the Christian Faith against such theological errors like Antinomianism. Now if such could be said about today’s American Baptist, could you imagine the difference in understanding Law and Grace?
