The style of the Serious Call is admirably adapted to its subject. It is serious, clear, and strong, but not graceful. There is never the slightest doubt about William Law's meaning. He conveys to the reader the exact idea that is in his own mind. The book is addressed to Christians, and it is, as its title implies, a Serious Call to be what they profess. The point is inevitable; it is driven home with extraordinary force, and Law's whole life gives weight to every word.
