Narrow Gate as Turnstile
The point: Beware of the attractive and popular alternative to the narrow gate, and especially of false prophets (including your own heart) who would tell you the gate or way is not so narrow.
The narrow gate is likened to a turnstile, emphasizing that people can only enter one at a time, stripped of anything that would hinder their entrance, highlighting the personal and humbling nature of conversion.
I am deeply desirous that you actually enter it. And so he graciously but with regal authority gives this imperative, enter this kingdom, but only one way to enter, by means of getting through a narrow gate, a turnstile-like entrance into the kingdom where people can only go in one at a time. They can only enter one at a time. They can only go in stripped of all that would hinder their entrance.
