(1), an English Baptist minister of the 18th century, was in early life a mechanic; but, brought under the influence of Gospel teaching, he studied, and became the minister of a Baptist congregation at London. He published a number of occasional Sermons and theological treatises (1763-1807). Of these, the most important was The Conquest of Canaan (Lond. 1797, 12mo). Of his occasional sermons, the one on Acts 14:7, deserves special mention, entitled The Gospel of our Salvation (Lond. 1796, 8vo). Besides, there were published three volumes of his sermons, one treating of The Character of Christ (1793, 8vo); the other two were edited by Thomas Palmer (1817, 2 vols. 8vo). John Martin is described by Ivimy (Baptists) as "a man of strong mental powers," and as a truly "evangelical preacher." See his Autobiography (1797, 12mo). See also Darling, Cyclop.
