Charles Ellicott Commentary Luke 13:24

"Strive to enter in by the narrow door: for many, I say unto you, shall seek to enter in, and shall not be able." — Luke 13:24 (ASV)

Strive to enter in at the strait gate.—See Notes on Matthew 7:13-14. Another instance of general teaching adapted to a special occasion. We note, however, the variation, strive to enter in—i.e., struggle as the wrestler struggles (the word being the same as that in 1 Corinthians 9:25; 1 Timothy 6:12), instead of the simple enter ye in, and the compression of the whole illustration.
