Now seeing the coming of the Lord Jesus Christ is so nigh, even at the doors, what doth this speak to all sorts of people (under heaven) but this?
Admonition 1. First, to see whether they have oil in their lamps or not; that is, to search and see, whether the Spirit of the Man Christ Jesus be in them or no; for he that hath not the Spirit of Christ in him, is none of Christ's (Rom 8:9). Thou that hast not the Spirit of Christ in thee, why, at that day (let thy profession be what it will) he will say to thee, Depart, I know you not (Matt 25), and if so, then thy latter end will be worse than thy beginning, as in 2 Peter 2:20.
Admonition 2. Then what will become of all the profane, ignorant, scoffers, self-righteous, proud, bastard-professors in the world? If the children of God shall 'scarcely be saved, where shall the ungodly, and the sinner appear?' (1 Peter 4:18).
Admonition 3. Then what will become of all those that creep into the society of God's people without a wedding garment on? Why, it will be said unto them, Friends, how came you hither? Take them, and bind them hand and foot, and cast them into utter darkness; 'There shall be weeping and gnashing of teeth' (Matt 22:11-13).
Admonition 4. Then what will become of all those that mock at the second coming of the Man Christ, as do the Ranters, Quakers, drunkards, and the like? Why read their doom in Matthew 24:50, 51, 'The Lord of that or these servants, shall come in a day when they look not for him, and in an hour that they are not aware of, and shall cut them asunder, and appoint them their portion with the hypocrites,' And 'there shall be weeping and gnashing of teeth.'
Admonition 5. Then what doth this speak to the Lord's own people? Surely this, that they should be in a watchful posture (Mark 13:37).
(1.) Watch therefore over your own hearts, least they should be over-charged with surfeiting and drunkenness, and the cares of this life, and so that day come upon you unawares; for as a snare shall it come upon all the dwellers upon the face of the earth, as it is in Luke 31:34-36.
(2.) Watch over the devil's temptations. Oh, have a care in the first place, lest by any means, as the serpent beguiled Eve, so your minds should be corrupted from the simplicity that is in Christ: And the rather, because at this day he is very busy with his doctrines, and his ministers; trying all ways, if by any means he might deceive you with fair speeches, and enticing carriages; what a fair shew in the flesh, yet denying the Lord, and refusing to be justified by the blood of Jesus the Son of Mary, the Son of God. Watch I say over the devil touching doctrines, for he labours as much this way as any way, for he knows that if he can but get you to lay a rotten foundation, he is sure of you, live as godly in your conceit as you will, and therefore, it is worth your observation, in that 24th of Matthew when Christ is speaking of the signs of his coming, he breaks forth with a warning word to his disciples, to beware of false teachers (v 4). The very first words that he answers to a question that his disciples put to him is this, 'Take heed that no man deceive you.' Again (v 11), 'And many false prophets shall rise, and shall deceive many.' And (v 24) he saith again, 'For there shall [come or] arise, false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.'
(3.) Take heed that he doth not deceive you in point of worship, that he make you not slight any of the ordinances of God; for if he do, he will quickly make way for another temptation.
(4.) Take heed also that you have not your lamps to trim when the bridegroom comes; if you have, you may peradventure be ashamed and blush before him at his coming (1 John 2:28). Therefore content not yourselves with a profession of Christ, and no more, for the devil may deceive, yea, doth deceive a professing people many times. And if he will deceive a professing generation, he must come in this manner: Under the name of Christ. With a fair shew in the flesh of outward holiness (Gal 6:12). He must come 'with good words and fair speeches' (Rom 16:18). Now though he come to drunkards, swearers, whore mongers, thieves, liars, murderers, and covetous persons, in his black colours; yet if he will come to deceive a professing party, he must appear like an angel of light (2 Cor 11:14). And the reason why souls are deceived by him in these his appearances, is, because they are not able to distinguish betwixt the law and the gospel, the convictions of conscience by the law only, and convictions by the Spirit, but do (though they profess the Lord Jesus) give ear to every wind of doctrine, and being unstable, as Peter saith, do fall into the temptations of the devil, in wresting the scriptures to their own destruction (2 Peter 3:16).
