Matthew 24:4

4.And Jesus answering said to them. They received an answer very different from what they had expected; for whereas they were eager for a triumph, as if they had already finished their warfare, Christ exhorts them to long patience. As if he had said, “You wish to seize the prize at the very outset, but you must first finish the course. You would draw down to earth the kingdom of God, which no man can obtain till he ascend to heaven.” Now while this chapter contains admonitions highly useful for regulating the course of our life, we see that, by a wonderful purpose of God, the mistake into which the apostles fell is made to turn to our advantage. The amount of the present instruction is, that the preaching of the Gospel is like sowing the seed, and therefore we ought to wait patiently for the time of reaping; and that it arises from improper delicacy or effeminacy, if we lose courage on account of the frost, or snow, or clouds of winter or other unpleasant seasons.

Take heed lest any man deceive you. There are two charges which Christ expressly gives to the disciples, to beware of false teachers, and not to be terrified by scandals. By these words he gives warning that his Church, so long as its pilgrimage in the world shall last, will be exposed to these evils. But they might be apt to think that this was inconsistent, since the prophets gave a widely different description of the future reign of Christ. Isaiah predicts that all will then be taught of God, (Isaiah 54:13.) The words of God are:

I will pour out my Spirit on all flesh;
and your sons and your daughters shall prophesy;
your young men shall see visions, and your old men shall dream dreams,
(Joel 2:28.)

A still more abundant light of understanding is promised by Jeremiah.

No longer shall any man teach his neighbor, nor a man his brother, saying, Know the Lord; for all shall know me from the least to the greatest, (Jeremiah 31:34.)

And, therefore, we need not wonder if the Jews expected, that when the Sun of righteousness had arisen, as Malachi (Malachi 4:2) had predicted, they would be entirely free from every cloud of error. Hence, also, the woman of Samaria said,

When the Messiah cometh, he will teach us all things,
(John 4:25.)

Now we know what splendid promises of peace, righteousness, joy, and abundance of all blessings, are to be found everywhere in Scripture. We need not, therefore, wonder if they expected that, at the coming of Christ, they would be delivered from commotions of war, from extortions and every kind of injustice, and, in short, from famine and pestilence.

But Christ warns them, that false teachers will henceforth give no less annoyance to the godly than false prophets gave to the ancient people; and that disturbances will be not less frequent under the Gospel than they formerly were under the Law. Not that those prophecies which I have just mentioned will fail to be accomplished, but because the full accomplishment of them does not immediately appear in one day; for it is enough that believers now obtain a taste of those blessings, so as to cherish the hope of the full enjoyment of them at a future period. And, therefore, they were greatly mistaken, who wished to hay at the commencement of the Gospel, an immediate and perfect exhibition of those things which we see accomplished from day to day. Besides, that happiness which the prophets ascribe to the reign of Christ, though it cannot be altogether annihilated by the depravity of man, is retarded or delayed by it. It is true that the Lord, in contending with the malice of men, opens up a way for his blessings through every obstacle; and, indeed, it would be unreasonable to suppose that what is founded on the undeserved goodness of God, and does not depend on the will of man, should be set aside through their fault.

Yet, that they may receive some punishment for their ingratitude he drops upon them in small measure his favors, which would otherwise flow on them in the richest abundance. Hence arises a labyrinth of evils, through which believers wander all their life, though they are pursuing the straight road to salvation, having Christ for their guide, who holds out to them the torch of his Gospel. Hence arises a multitude of combats, so that they have a hard warfare, though there is no danger of their being vanquished. Hence arise disturbances so numerous and so sudden, that they are kept in perpetual uneasiness, though, resting on Christ, they remain firm to the end. And since Christ enjoins his disciples to beware of impostures, let us know that the means of defense will not be wanting, provided that they are not wanting to themselves. (127) And therefore, whatever arts Satan may employ, let us entertain no doubt that we shall be safe from them, if every one of us keep diligent watch on his own station.
