<P> Whittle wrote mostly under the pseudonym "El Nathan" although editors of later hymnals routinely credit his actual name . Of his approximately 200 hymns, "I Know Whom I Have Believed" and "Showers of Blessing" are among the most familiar . James McGranahan wrote the tunes for both of those and for Whittle's "Banner of the Cross" as well . The name of the tune associated with "I Know Whom I Have Believed" is EL NATHAN, Whittle's pseudonym . The tune for Whittle's "Moment by Moment" (first line "Dying with Jesus") was composed by Whittle's daughter Mary "May" Whittle Moody . </P> <Ul> <Li> Memoirs of Philip P. Bliss edited by D.W.
