To God the only wise, Our Saviour and our King. I. Watts. [Preserving Grace.] First published in his Hymns and Spiritual Songs, 1707 (2nd ed. 1709, Bk. i., No. 51), in 5 stanzas of 4 lines. It is found in most of the early hymnbooks, especially those of a Calvinistic type, as the collections of G. Whitefield, M. Madan, and others, but to modern hymnals, except in America, it is not so well known, although still found in several books.
