The metaphor of a walk or journey developed from the lives of the patriarchs, particularly from Abraham. It refers not only to his actual movement from place to place, but also to his journey with God. His life is retold around his “walk”—his life of sojourning where God led him and, at times, where He did not. When Abraham lived confidently in full assurance of God’s promises, things went well for him. When He attempted to supplement those promises or work toward them in his own creativity and timing, things went poorly. These truths are as real for us today as they were for Abraham thousands of years ago.
