This verse should have been connected with the following chapter

The parable there spoken is expressly to illustrate this sentiment. See it explained in the notes at Matthew 20:16.

Remarks On Matthew 19

1. We should not throw ourselves unnecessarily in the way of the enemies of religion, Matthew 19:1. Jesus, to avoid the dangers to which he was exposed, left Jerusalem, and passed over to the other side of the Jordan. If duty calls us to remain in the presence of our enemies and the enemies of religion, we should do it. If we can do them good, we should do it. If our presence will only provoke them to anger and bitterness, then we should turn aside. Compare the notes at Matthew 10:23.

2. People will seek every occasion to ensnare Christians, Matthew 19:3. Questions will be proposed with great art, and with an appearance of sincerity, only for the purpose of leading them into difficulty. Cunning men know well how to propose such questions, and triumph much when they have perplexed believers. This is often the boast of people of some standing, who think they accomplish the great purposes of their existence if they can confound other people, and think it signal triumph if they can make others as miserable as themselves.

3. We should not refuse to answer such persons with mildness, when the Bible has settled the question, Matthew 19:4-6. Jesus answered a captious question, proposed on purpose to ensnare him. We may often do much to confound the enemies of religion, and to recommend it, when without passion we hear their inquiries, and deliberately inform them that the question has been settled by God. We had better, however, far better, say nothing in reply, than to answer in anger or to show that we are irritated. All the object of the enemy is gained if he can make us angry.

4. People will search and pervert the Bible for authority to indulge their sins and to perplex Christians, Matthew 19:7. No device is more common than to produce a passage of Scripture known to be misquoted or perverted, yet plausible, for the purpose of perplexing Christians. In such cases, the best way, often, is to say nothing. If unanswered, people will be ashamed of it; if answered, they gain their point, and are ready for debate and abuse.

5. We learn from this chapter that there is no union so intimate as the marriage connection, Matthew 19:6. Nothing is so tender and endearing as this union appointed by God for the welfare of man.

6. This union should not be entered into slightly or rashly. It involves all the happiness of this life and much of that to come. The union demands:

(1) congeniality of feeling and disposition;

(2) of rank or standing in life;

(3) of temper;

(4) similarity of acquirements;

(5) of age;

But many that are first, etc. - The Jews, who have been the first and most distinguished people of God, will in general reject the Gospel of my grace, and be consequently rejected by me. The Gentiles, who have had no name among the living, shall be brought to the knowledge of the truth, and become the first, the chief, and most exalted people of God. That this prediction of our Lord has been literally fulfilled, the present state of the Christian and Jewish Churches sufficiently proves. To illustrate this fully, and to demonstrate that the Jews and Gentiles were now put on an equal footing by the Gospel, our Lord speaks the following parable, which has been unhappily divided from its connection by making it the beginning of a new chapter.

But many that are first shall be last,.... This may refer unto, or be occasioned by, either the young ruler; signifying that he, and others like him, who were superior in riches and honour, were first in this world, of the first rank and figure, should be the last in the world to come:

and the last shall be first; the apostles, who were last in this world, being poor, mean, and abject, should be the first in the other: or to the Scribes and Pharisees, who were in the chief place, and highest esteem, in the Jewish church, and yet least in the kingdom of heaven; when, on the other hand, the publicans and sinners, who were in the lowest class, and in least esteem, went first into it: or to the case of persecution, when some, who seem most forward to endure it at a distance, when it comes nearer, are most backward to it; whilst others, who were most fearful of it, and ready to shrink at the thoughts of it, most cheerfully bear it: or to the apostles themselves, one of which, who was now first, Judas, should be last; and the apostle Paul, who was last of all, as one born out of due time, should be first: or to Jews and Gentiles, intimating, that the Jews, who were first in outward privileges, would be rejected of God for their unbelief, and contempt of the Messiah; and the Gentiles, who were last called, should be first, or chief, in embracing the Messiah, professing his Gospel, and supporting his interest. This sentence is confirmed, and illustrated, by a parable, in the following chapter.

{8} But many that are first shall be last; and the last shall be first.

(8) To have begun well, and not to continue unto the end, is not only unprofitable, but also hurts very much.

19:30 Many that are first shall be last, etc. There will be reversals; those rich on earth, but poor hereafter; those high in station, degraded hereafter; and the lowly on earth, exalted hereafter. The right man to follow any cause, be it what it will, is he who loves it well enough to fling to it everything he has in the world, and then think that not enough, and so fling himself after it. This last item often weighs down the scales in heaven, and the man gets what he gave himself for.

19:30 But many first - Many of those who were first called, shall be last - Shall have the lowest reward: those who came after them being preferred before them: and yet possibly both the first and the last may be saved, though with different degrees of glory. Mt 20:16; Mark 10:31; Luke 13:30.

19:23-30 Though Christ spoke so strongly, few that have riches do not trust in them. How few that are poor are not tempted to envy! But men's earnestness in this matter is like their toiling to build a high wall to shut themselves and their children out of heaven. It should be satisfaction to those who are in a low condition, that they are not exposed to the temptations of a high and prosperous condition. If they live more hardly in this world than the rich, yet, if they get more easily to a better world, they have no reason to complain. Christ's words show that it is hard for a rich man to be a good Christian, and to be saved. The way to heaven is a narrow way to all, and the gate that leads into it, a strait gate; particularly so to rich people. More duties are expected from them than from others, and more sins easily beset them. It is hard not to be charmed with a smiling world. Rich people have a great account to make up for their opportunities above others. It is utterly impossible for a man that sets his heart upon his riches, to get to heaven. Christ used an expression, denoting a difficulty altogether unconquerable by the power of man. Nothing less than the almighty grace of God will enable a rich man to get over this difficulty. Who then can be saved? If riches hinder rich people, are not pride and sinful lusts found in those not rich, and as dangerous to them? Who can be saved? say the disciples. None, saith Christ, by any created power. The beginning, progress, and perfecting the work of salvation, depend wholly on the almighty power of God, to which all things are possible. Not that rich people can be saved in their worldliness, but that they should be saved from it. Peter said, We have forsaken all. Alas! it was but a poor all, only a few boats and nets; yet observe how Peter speaks, as if it had been some mighty thing. We are too apt to make the most of our services and sufferings, our expenses and losses, for Christ. However, Christ does not upbraid them; though it was but little that they had forsaken, yet it was their all, and as dear to them as if it had been more. Christ took it kindly that they left it to follow him; he accepts according to what a man hath. Our Lord's promise to the apostles is, that when the Son of man shall sit on the throne of his glory, he will make all things new, and they shall sit with him in judgement on those who will be judged according to their doctrine. This sets forth the honour, dignity, and authority of their office and ministry. Our Lord added, that every one who had forsaken possessions or comforts, for his sake and the gospel, would be recompensed at last. May God give us faith to rest our hope on this his promise; then we shall be ready for every service or sacrifice. Our Saviour, in the last verse, does away a mistake of some. The heavenly inheritance is not given as earthly ones are, but according to God's pleasure. Let us not trust in promising appearances or outward profession. Others may, for aught we know, become eminent in faith and holiness.
