But know this. Another similitude is now employed by Christ, in exhorting his disciples to keep diligent watch; for if any person shall hear that robbers are prowling in the night, fear and suspicion will not allow him to sleep. Since, therefore, we are informed that Christ's coming will be sudden and unexpected, like that of a robber, and since we are expressly forewarned that we must always watch, lest he come upon us when asleep, and we be swallowed up with the ungodly, there is no excuse for our indolence; more especially since there is reason to dread not only a breach of the wall, and a loss of our property, but a deadly wound to ruin our soul, unless we are on our guard. The tendency of these words therefore is, that the warning of Christ should arouse us; for, though the last judgment be delayed for a long time, yet it hangs over us every hour; and, therefore, when there is ground for alarm, and when danger is near, it is unreasonable that we should be sluggish.

Be ye also ready - Luke Luke 21:36 says that he charged them to pray always, that they might be accounted worthy to escape those things - the judgments coming upon the wicked - and to stand before the Son of man - that is, to stand there approved by him, or to be admitted to his favor. He also charged them Luke 21:34 to take heed and not to suffer their hearts to be overcharged with surfeiting, or too much eating, or drunkenness, or the cares of this life, lest that day should come upon them unawares; things improper if there were no judgment - especially mad and wicked when the judgment is near.

Therefore be ye also ready,.... Or prepared for the coming of the son of man; which as it is said to be like a thief in the night, expresses the suddenness of it, may excite to watchfulness and readiness; which readiness is to be understood, not of a readiness to do the will and work of God, though this is absolutely necessary; as to watch and pray, to hear the word preached, to confess Christ, and give a reason of the hope that is in us, to communicate to the support of the cause and interest of Christ, and to suffer for his sake; but of a preparedness to meet the Lord in the way of his judgments, when desolating judgments are coming on the earth, such as these in Jerusalem; by faith and trust in the power, providence, and care of God; by humiliation before him, and resignation to his will: and if this can be applied to a readiness for a future state after death; for the second coming of Christ, and last judgment; this lies not in a dependence on the absolute mercy of God; nor in an external humiliation for sin; nor in an abstinence from grosser sins, or in mere negative holiness; nor in any outward, legal, civil, and moral righteousness; nor in a submission to Gospel ordinances; nor in a mere profession of religion; but in being in Christ, having on his righteousness, and being washed in his blood; and also in regeneration and sanctification, in having true knowledge of Christ, and faith in him; for all which it becomes men to be concerned, as also all believers to be actually, as well as habitually ready; being in the lively exercise of grace, and cheerful discharge of duty, though without trusting to either. And such a readiness in either branch of it, is not of themselves, but lies in the grace of God, which gives a meetness for glory; and in the righteousness of Christ, the fine linen, clean and white, which being granted by him, his people are made ready for him: and as for their faith, and the exercise of it, and their constant performance of duty, these are not from the strength of nature and the power of freewill, but from the Spirit of God and his grace; who makes ready a people prepared for the Lord, and all according to the ancient settlements of grace, in which provision is made for the vessels of mercy, afore prepared for glory: though there should be a studious concern in men for such readiness, for nothing is more certain than death, and nothing more uncertain than when it will be; and after death, no readiness can be had, but he that is then righteous, shall be righteous still, and he that is filthy, shall be filthy still, and a deathbed is by no means to be trusted to; and though a person may not be snatched away suddenly, but may have space given him to repent, yet if grace is not given him, to repent and believe in Christ, he never will; the grave is ready for men, and in a little time all will be brought to this house, appointed for all living, where there is no wisdom, knowledge, and device; and therefore whatever we are directed to do, should be now done, with all that might, and strength, and grace, that is given us; to which may be added, that after death comes judgment; the day is fixed, the judge is appointed, and all must stand before his judgment seat; and nothing is more sure than that Christ will come a second time, to judge both quick and dead; and happy will those be that are ready; they will be received by Christ into everlasting habitations, and be for ever with him: and miserable will those be, who will not be ready, who will not have the oil of grace in their hearts with their lamps, nor the wedding garment on them; they will be shut out, and bid to depart into everlasting burnings: how fit and proper is such an advice and exhortation as this, "be ye also ready". A readiness the Jews report Bath Kol, or the voice from heaven, gave out concerning the Israelites,
"Bath Kol (say (y) they) went out, and said to them, , "ye are all of you ready for the life of the world to come".
And elsewhere it is said of Bath Kol, that it went forth and affirmed of some particular Rabbins, that they were ready for eternal life; as of Ketiah bar Shalom, R. Eleazar ben Durdia, and R. Chanina (z):
for in such an hour as ye think not, the son of man cometh: this is true of his coming in power to destroy Jerusalem, and of his second coming to judgment. The Jews say much the same of the coming of the Messiah, whom they expect:
"there are three things, they say (a), which come, "without knowledge", or unthought of, at an unawares; and they are these, the Messiah, anything that is found, and a scorpion.

Be ye also ready. The duty enjoined is not to watch for Christ, but to watch ourselves to see that we are ready.
