John Colquhoun (1748-1827) was a minister in the Church of Scotland whose sermons and writings reflect those of the Marrow brethren of the Secession church. Colquhoun‘s writings are theologically astute and intensely practical. He wrote on the core doctrines of the gospel, particularly on experiential soteriology. In this book, Colquhoun helps us understand the precise relationship between law and gospel. He also impresses us with the importance of knowing this relationship. Colquhoun especially excels in showing how important the law is as a believer‘s rule of life without doing injury to the freeness and fullness of the gospel. By implication, he enables us to draw four practical conclusions: 1) the law shows us how to live, 2) the law as a rule of life combats both antinomianism and legalism, 3) the law shows us how to love, and 4) the law promotes true freedom.
