“Be dressed for action and have your lamps lit; be like those who are waiting for their master to return from the wedding banquet so that they may open the door for him as soon as he comes and knocks.”
Luke 12:35-48
Earlier in Luke 12, Jesus seems to be saying to the people who collected around him, “Do not be overly invested in the details of your life.” He wasn’t saying that we should resign from life, but rather that we should be careful how we oriented our lives.
Furthermore, don’t fret about what you should say in defense of your faith. Don’t collect wealth. Don’t worry about how you will get along in this life. And be generous with what you have.
Jesus taught his disciples to live expectantly. Much the way a person expecting a trip to Europe would live. They would spend their time picking the right luggage, reading travel guides, buying airline tickets, and in other way getting ready for the trip. Thus when the day arrived, they merely set in motion the plan for which they had been getting ready.
