Banquet Hall with Small Door
Driving home: You must be ready to be stripped of all of the padded, down-filled clothing of your native pride and self-sufficiency, prepared to be stripped down to the naked bare sinner that you are.
The kingdom is likened to a vast banquet hall with a disproportionately small, narrow, and low door, illustrating that entrance into God's kingdom is exclusive and requires humility and shedding of self-righteousness.
Because down in verse 29 he says that those who come from east and west, north and south shall literally recline in the kingdom. It's the picture of a vast, wide, spacious, expansive banquet hall and people are all reclining eastern fashion as they feast together. But there's a strange thing about this large, expansive, ornate banquet hall. It has a disproportionately small door.
