Would you consider looking at Matthew 7:13-14 in a way you may not have been taught?
"Enter by the narrow gate; for wide is the gate and broad is the way that leads to destruction, and there are many who go in by it. Because narrow is the gate and difficult is the way which leads to life, and there are few who find it."
That is, He is urging His disciples to consider the present situation they witness round about them. They are to look around them and see that so many souls are presently perishing, so few men are seeking righteousness and salvation. What will they do about this sad predicament? Do they love Him enough to seek its reversal? Christ's challenge to them is ethical.
In John 4:35 He urges the dim-eyed disciples to see that there was much work to be done: "Do you not say, 'There are still four months and then comes the harvest'? Behold, I say to you, lift up your eyes and look at the fields, for they are already white for harvest!” In Matthew 7 He warns against false prophets that will arise among the people (Matt. 7:15-20). Then He warns that a man must hear and act upon His words (Matt. 7:21-27). His disciples must feel the horror of the present vastness of the multitude entering the broad way to destruction.
Certainly the gate is narrow: only He is the Way, the Truth, and the Life (John 14:6). But His statement in Matthew 7:13-14 does not imply that it will always and forever be the case that few will be saved in every era of history. In fact, there are numerous indications, as we have seen, that a great multitude of men will be saved, that the world as an organic system will experience the redeeming work of Christ, that all of His enemies will be subdued.
The Fall of Adam has taken an enormous toll upon the race of man, to be sure. But the resurrection and ascension of Christ will surely outstrip the effects of the Fall as history unfolds. This is why He delays His coming, so that He may gather the elect in. "The Lord is not slack concerning His promise, as some count slackness, but is longsuffering toward us, not willing that any should perish but that all should come to repentance.” (2 Peter 3:9)
That the Lord is using the statement in Matthew 7:13-14 as an ethical prod rather than a prophetic expectation is evident from His use of it in another context. In Luke 13:23, we read: "Then one said to Him, 'Lord, are there few who are saved?' And He said to them, 'Strive to enter through the narrow gate, for many, I say to you, will seek to enter and will not be able. When once the Master of the house has risen up and shut the door, and you begin to stand outside and knock at the door, saying, "Lord, Lord, open for us,” and He will answer and say to you, "I do not know you, where you are from.” “ (Luke 13:24-25). Here He refuses to answer the question regarding the number of the saved. This was one of those questions that was asked in order to evade Christ's call to righteousness. The Lord was not prone to allow such rabbit trails to lead Him away from calling men to commitment. His statement in Matthew 7:13-14 served His purpose. Let us avoid this particular rabbit trail.
