“Strive to enter through the narrow door”
Make every effort to enter through the narrow door. For many, I tell you, will try to enter and will not be able. (Luke 13:24 BSB)
What it sounds like today
A vague image of difficulty.
The cultural key
Walled cities had broad main gates handling crowds, animals, and cargo, and small side doors admitting one person at a time, on foot, carrying little. Behind the image stands Israel's classic 'two ways' teaching: 'I have set before you life and death… choose life' (Deuteronomy 30:19; Psalm 1; Jeremiah 21:8). Luke has a door, not Matthew's gate, and the next verses show whose door: a master of a house who rises and shuts it, leaving latecomers knocking. The city-gate image becomes a banquet-house image, and it flows into the same feast scene where outsiders recline with Abraham while insiders stand outside (13:25–29).
Recovered meaning
The crowd's route is easy precisely because it's the default. Life's entrance takes deliberate choice, travels light, and must be found rather than drifted into: 'few there be that find it.'
