"The law and the gospel are the principal parts of divine revelation; or rather they are the center, sum, and substance of all the other parts of it. Every passage of sacred Scripture is either law or gospel, or is capable of being referred either to one or to the other... If then a man cannot distinguish aright between the law and the gospel, he cannot rightly understand so much as a single article of divine truth. If he does not have spiritual and just apprehensions of the holy law, he cannot have spiritual and transforming discoveries of the glorious gospel; and, on the other hand, if his view of the gospel is erroneous, his notions of the law cannot be right." - John Colquhoun (1748-1827)
John Colquhoun was a minister in the Church of Scotland whose sermons and writings reflect those of the Marrow brethren of the Secession church.
