“So the woman arose and did according to the word of the man of God” (v2). The Shunammite woman had seen God do miracles both privately (raising her son from the dead) and publicly through Elisha, and so she was obedient when Elisha told her to flee the famine and live in “the land of the Philistines” for seven years. Her experience with the Lord gave her faith for the new challenge. When she and her son returned, she reclaimed their land.
God does “great things” for us (v4) not just to help us in the moment, but also to increase our faith so that we trust Him more and more.
