Because strait is the gate - Instead of οτι because, I should prefer τι how, which reading is supported by a great majority of the best MSS., versions, and fathers. How strait is that gate! This mode of expression more forcibly points out the difficulty of the way to the kingdom. How strange is it that men should be unwilling to give up their worldly interests to secure their everlasting salvation! And yet no interest need be abandoned, but that which is produced by injustice and unkindness. Reason, as well as God, says, such people should be excluded from a place of blessedness. He who shows no mercy (and much more he who shows no justice) shall have judgment without mercy. James 2:13.
Few there be that find it - The strait gate, στενη πυλη, signifies literally what we call a wicket, i.e. a little door in a large gate. Gate, among the Jews, signifies, metaphorically, the entrance, introduction, or means of acquiring any thing. So they talk of the gate of repentance, the gate of prayers, and the gate of tears. When God, say they, shut the gate of paradise against Adam, He opened to him the gate of repentance. The way to the kingdom of God is made sufficiently manifest - the completest assistance is promised in the way, and the greatest encouragement to persevere to the end is held out in the everlasting Gospel. But men are so wedded to their own passions, and so determined to follow the imaginations of their own hearts, that still it may be said: There are few who find the way to heaven; fewer yet who abide any time in it; fewer still who walk in it; and fewest of all who persevere unto the end. Nothing renders this way either narrow or difficult to any person, but sin. Let all the world leave their sins, and all the world may walk abreast in this good way.

Because (c) strait [is] the gate, and narrow [is] the way, which leadeth unto life, and few there be that find it.
(c) The way is straight and narrow: we must pass through this rough way and suffer, endure, be changed and so enter into life.

Because strait is the gate, and narrow is the way,.... And so, difficult to enter in at; and when entered, the way is unpleasant to the flesh to walk in, being hedged up on each side with afflictions and tribulations; and moreover, is like the "narrow place", or , "the strait place", as the Septuagint in Numbers 22:26 render it; in which the angel that met Balaam stood; and in which there was no turning to the right hand or the left; and such is the way to eternal happiness. The great encouragement to walk on in it is, because it is that way
which leadeth unto life: unto eternal life: it certainly leads thither; it never fails of bringing persons to it; believers in Christ, all that walk in Christ the way, though they are said to be "scarcely" saved, by reason of their afflictions and trials, they meet with in their way to the kingdom; yet they are, and shall be certainly saved: they shall be safely brought to glory; which will be an abundant recompense for all the troubles and sorrows that have attended them in their journey.
And few there be that find it; the way, and so consequently the life it leads to. "The gate is strait"; small and little, and so unobserved: there is but one way to heaven, and the generality of men neglect it. "The way is narrow", and so disagreeable; the company few, and not engaging. Men choose large gates, broad ways, and much company. The flesh loves to walk at liberty, unconfined, and uncontrolled, and with a multitude to do evil: hence, Zion's ways are thin of passengers; a small number, comparatively speaking, walk thereto, and will be saved; a remnant, a little flock, a little city, and few men in it. It is asked in the Talmud (q),
"why is the world to come created with "jod?" (the least of the letters in the "Hebrew alphabet") the answer is, because , "the righteous which are in it are few".''
Some read the words, as the Syriac, Arabic, and Vulgate Latin, with a note of admiration, "how strait is the gate!" &c. and so some copies.
(q) T. Bab. Menachot, fol. 29. 2.

Because strait is the gate, and narrow is the way, which leadeth unto life--In other words, the whole course is as difficult as the first step; and (so it comes to pass that).
few there be that find it--The recommendation of the broad way is the ease with which it is trodden and the abundance of company to be found in it. It is sailing with a fair wind and a favorable tide. The natural inclinations are not crossed, and fears of the issue, if not easily hushed, are in the long run effectually subdued. The one disadvantage of this course is its end--it "leadeth to destruction." The great Teacher says it, and says it as "One having authority." To the supposed injustice or harshness of this He never once adverts. He leaves it to be inferred that such a course righteously, naturally, necessarily so ends. But whether men see this or no, here He lays down the law of the kingdom, and leaves it with us. As to the other way, the disadvantage of it lies in its narrowness and solicitude. Its very first step involves a revolution in all our purposes and plans for life, and a surrender of all that is dear to natural inclination, while all that follows is but a repetition of the first great act of self-sacrifice. No wonder, then, that few find and few are found in it. But it has one advantage--it "leadeth unto life." Some critics take "the gate" here, not for the first, but the last step in religion; since gates seldom open into roads, but roads usually terminate in a gate, leading straight to a mansion. But as this would make our Lord's words to have a very inverted and unnatural form as they stand, it is better, with the majority of critics, to view them as we have done. But since such teaching would be as unpopular as the way itself, our Lord next forewarns His hearers that preachers of smooth things--the true heirs and representatives of the false prophets of old--would be rife enough in the new kingdom.

For strait is the gate. What is it, Augustine asks, that makes this gate so strait to us? It is not that it is strait, or narrow, in itself, but that we want to take in our pride, our self-will, our darling sins.
Few there be that find it. It has been to be sought. The reason that men do not find it is not because it is hard to find, but because they prefer to walk in the broad way.
