endurance: The Greek noun hy·po·mo·neʹ is used in the Scriptures to denote courageous, steadfast, or patient “endurance” that does not lose hope in the face of obstacles, persecutions, trials, or temptations. The related verb hy·po·meʹno, rendered “to endure,” literally means “to remain (stay) under.” It is often used in the sense of “remaining instead of fleeing; standing one’s ground; persevering; remaining steadfast.”​—Mt 10:22; Ro 12:12; Heb 10:32; Jas 5:11.

preserve your lives: Or “acquire (gain) your lives (souls).” The meaning of the Greek word psy·kheʹ, traditionally rendered “soul,” has to be determined by the context. (See Glossary, “Soul.”) It often refers to a person’s life, present or future. In this context, it has been rendered “your future lives” or “your real life.”
