O 'tis enough, my God, my God. C. Wesley. [Penitence and Pardon.] Given inHymns on God's Everlasting Love, 1741, No. 9, in 11 stanzas of 6 lines (Poetical Works, 1868-72, vol. iii. p. 18). In the Wesleyan Hymn Book, 1780, Nos. 163 and 164 were included therefrom, the first being stanzas i.-iii., and the second, "O God, if Thou art love indeed," stanzas viii.-xi. These hymns have been repeated in other collections. In the first number of the Arminian Magazine, 1778, stanzas i.-ix. were given with the title "Salvation depends not on Absolute Decrees." This title is somewhat defiant, when we remember that Toplady's Gospel Magazine was in course of issue at the same time.
