Luke 13:23

Luke 13:23. And he said unto them, Strive to enter in at the strait gate: for many, I say unto you, wilt seek to enter in, and shall not be able.

Make a push for it; agonize for it; for many will seek - not strive, but merely seek. Or, to put another meaning into it, strive now to enter in at the strait gate, for many will be unable, when it is too late; and that, doubtless, is the sense of the passage.
