15:58 be steadfast. In the face of false teaching and various temptations, the hope of the Resurrection should encourage the Corinthians to persevere in their faith. The exhortation to be “immovable,” however, does not imply inactivity. On the contrary, the Corinthians must be fully active in “the work of the Lord.” We can become easily discouraged by thinking that our labor may come to nothing (Gal. 2:2; Phil. 2:16; 1 Thess. 3:5), but we can remember the promise that when God creates the new heavens and new earth His people will enjoy the fruits of their toil, and see that their efforts are never “in vain” (Is. 65:17–25).
