“By your patient endurance,
You will gain
ἐν τῇ ὑπομονῇ ὑμῶν κτήσεσθε τὰς ψυχὰς ὑμῶν
Luke indicated that Jesus said that by their patient endurance (ἐν τῇ ὑπομονῇ ὑμῶν), they would gain or acquire (κτήσεσθε) their lives (τὰς ψυχὰς ὑμῶν). There is something similar in Mark, chapter 13:13, and Matthew, chapter 10:22, and chapter 24:13. Mark indicated that endurance was important. Jesus said that the one who endured or stayed firm to the end would be saved (ὁ δὲ ὑπομείνας εἰς τέλος, οὗτος σωθήσεται). Matthew had the same idea in chapter 10:22. If they were able to be endure to the end (ὁ δὲ ὑπομείνας εἰς τέλος), they would be saved, rescued, or healed (οὗτος σωθήσεται). Jesus said that the one who endured or stayed firm to the end would be saved (ὁ δὲ ὑπομείνας εἰς τέλος, οὗτος σωθήσεται). Luke did not use the word saved (σωθήσεται) but gained or acquired (κτήσεσθε) their lives. Are you good at endurance?
