Parable of the Master's return
Luke 12:35–40 explains that those who wish to live in God's kingdom need to be ready for its arrival. Jesus has told His disciples to hold their integrity more tightly than their lives (Luke 12:1–12). He has taught them to not worry about wealth or even the necessities of life. Instead, they should trust God for their needs while they wait like servants for their master's return (Luke 12:13–34). Next, He explains that leaders in God's kingdom will have even more responsibilities (Luke 12:41–48). Matthew and Mark also touch on the theme (Matthew 24:43–44; 25:1–12; Mark 13:34–37).
