Jesus said to His disciples, “Whoever seeks to preserve his life will lose it, but whoever loses his life will keep it” (Luke 17:33).
This isn’t talking about physical life. In other words, it’s not saying don’t try to stay alive. This is about a spiritual reality. The unbeliever lives only for this life. It’s about trying to live the most enjoyable life possible, depending on what that means to him. Ultimately, they get their reward in this life, provided that they accomplish their goals. But unless they repent of their sins and trust in Jesus, they will lose their life and experience an eternal death.
On the other hand, “whoever loses his life will keep it.” What does it mean, then, to lose one’s life? Matthew sheds some light on this. Jesus says in that account, “whoever loses his life for My sake will find it“. And that is what Luke is talking about, as well. Again, this isn’t talking about martyrdom, but instead trusting Jesus with our lives. Giving it over to Him. We surrender our lives to Him, and as a result we find true life, even eternal life.
