Rueben P. Job (1922?-2015) was a retired bishop of the United Methodist Church and former World Editor of The Upper Room. A pioneer in spiritual formation for his denomination, he wrote numerous books on the spiritual life and developed several spiritual enrichment programs. Bishop Job and his friend Norman Shawchuck coauthored A Guide to Prayer for Ministers and Other Servants as a result of their own hunger for God and for a resource that could be their constant companion on the journey toward a deeper and more consistent relationship with God. This was the first in the four-volume Guide to Prayer series. A native of North Dakota, Rueben and his wife, Beverly, made their home in Nashville, Tennessee. Marjorie J.
