First, Now I shall lay down several grounds, not only why errors are broached in the world; but also, why so many are carried away with them.
1. One ground, why so many errors do from time to time come into the world, is because those that are not indeed of the planting of the Lord's right hand, might be rooted out (Matt 15:13). Now these are many times carried away by deceivable doctrines: And truly in this our God hath both a care of his own glory, and of his church's welfare. For first, should they not be swept away by some heresy or other, there might be great dishonour brought to his name by their continuing among his people: And secondly, that he might take away such grievances as such may bring, had they continued still in the society of his children.
2. Another ground why the Lord doth suffer such errors to come into the world is, because, those that are Christians indeed might be approved and appear (1Cor 11:19). "For there must be also heresies among you, that they which are approved may be made manifest." Should not the Lord go this way to work (sometimes) there would be many that would make people believe that they are Christians, and yet are not. And again, that he might make it appear, that though there be heretics, yet he hath a people, enabled by his Spirit, to contradict, and oppose them, and plead to the truth of our Lord Jesus Christ, and his glorious gospel against them.
3. Another ground why the Lord doth suffer, yea, even send delusions among the people, is, That those who were so idle and slothful, as not to seek after the Lord Jesus Christ in sincerity, might be taken away, and violently possessed with error, and be made to run greedily after the same; that they might smart the more for their neglect of the truth. For always, those who were lazy in seeking after the truth when it was proffered, and afterward hasty after the doctrine of devils, when that is declared to them, shall be sure to have their latter behavior to rise up in judgment against them, in that when the truth was proffered to them they were idle and did not receive it, and yet when delusion did proffer itself, they were industrious, and labouring. Now mark, that they all might be damned who believed not the truth, but had pleasure in unrighteousness; because they received not the truth in the love of it, that they might be saved. And for this cause God shall send them strong delusions, that they might believe a lie, and be dammed (2Thess 2:10-12).
Second, Now in the second place, why so many are so easily carried away with errors in this day: the grounds are these That follow.
1. Because men count it enough to be professors of the truth, without seeking to be possessors of the same. Now because men are but only professors of the truth, not having it in their hearts in reality, they are carried away with an error, if it come in never so little power, more that the truth they profess. And this is the reason why so many are carried away with the errors that are broached in these days, because they have not indeed received the Lord Jesus by the revelation of the Spirit, and with power, but by the relation of others only; and so having no other witness to set them down withal, but the history of the word, and the relation of others concerning the truth contained therein, (though the knowledge of the truth this way shall abundantly aggravate their damnation) yet they having not had the Spirit of the Lord to confirm these things effectually unto them, they are carried away with delusions.
2. Another reason why so many are carried away with delusions, is, those differences that are among the children of God about smaller matter. O Friends! how is the hand of the enemy strengthened by our carnality, while one saith, I am of Paul; and another, I am of Apollos; many a poor soul is carried away with delusion. And why so? They are not satisfied that this is the truth, because the children are at difference among themselves, about some outward things. And again, it makes those that are not so desperately possessed with a spirit of delusion, as are others, but are mere moral men: I say it makes them to say within themselves, and one to another; There are so many sects and judgments in the world, that we cannot tell which way to take. And therefore you that have the Spirit, pray that these things may cease, least you blush for your folly, at the appearing of Jesus our Lord.
3. The pride, covetousness, and impiety of hypocrites, and carnal professors, are great stumbling-blocks to the poor world; and the cause why many at this day do drink down so greedily a deluding doctrine, and especially if it come with a garment of pretended holiness. But as for these, they shall go to their place in their time, with the curse of the Almighty poured out upon them, for their casting of stumbling-blocks before the simple by their loose conversation, if they do not hastily repent of their wickedness, and close in reality with our blessed Lord Jesus.
4. Another reason why delusions do so easily take place in the hearts of the ignorant, is, because those that pretend to be their teachers, do behave themselves so basely among them. And indeed I may say of these, as our Lord said of the Pharisees in another case, all the blood of the ignorant, from the beginning of the world, shall be laid to the charge of this generation. They that pretend they are sent of the Lord, and come, saying, Thus saith the Lord; we are the servants of the Lord, our commission is from the Lord (by succession) and the like; I say, these pretending themselves to be the preachers of truth, (but are not ) do by their loose conversation, render the doctrine of God, and his Son Jesus Christ, (by whom the saints are saved) contemptible, and do give the adversary mighty encouragement, to cry out against the truths of our Lord Jesus Christ, because of their wicked walking. Now shall not his soul be avenged on such a nation as this, who pretend to be teachers of the people in goodness, when, as for the most part of them, they are the men, that at this day do so harden their hearers, such ill examples, that none goeth beyond them for impiety. As for example; Would a parishioner learn to be proud? he or she need look no farther than to the priest, his wife and family; for there is a notable pattern before them. Would the people learn to be wanton, they may also see a pattern among their teachers. Would they learn to be drunkards? they may also have that from some of their minister; for indeed they are ministers in this, to minister ill example to their congregations. Again, would the people learn to be covetous, they need but look to their minister, and they shall have a lively, or rather a deadly resemblance set before them, in both riding and running after great benefices, and parsonages by night and by day. Nay, they among themselves will scramble for the same. I have seen, that so soon as a man hath but departed from his benefice as he calls it, either by death or out of covetousness of a bigger, we have had one priest from this town, and another from that, so run, for these tithe-cocks and handfuls of barley, as if it were their proper trade, and calling, to hunt after the same. O wonderful impiety and ungodliness! are you not ashamed of your doings? If you say no, it is (perhaps) because you are given over of God to a reprobate mind (Read Romans 1). towards the end. As it was with them, so (it is to be feared) it is with many of you, who knowing the judgments of God, that they who do such things are worthy of death, not only do the same, but have (as I may so say) pleasure also in them that do them. And now you that pretend to be the teachers of the people in verity and truth, though we know that some of you are not: Is it a small thing with you, to set them you say are your flock such an example as this. Were ever the Pharisees so profane; to whom Christ said, ye vipers, how can ye escape the damnation of hell; doth not the ground groan under you? surely, it will favour you no more than it favoured your fore-runners. Certainly the wrath of God lies heavy at your doors, it is but a very little while, and your recompense shall be upon your own head. And as for you that are indeed of God among them, though not of them; separate yourselves. Why should the righteous partake of the same plagues with the wicked? O ye children of the harlot! I cannot well tell how to have done with you, your stain is so odious, and you are so senseless, as appears by your practices. But I shall at this time forbear, having in some measure discharged my conscience according to the truth against you; hoping if God do give me opportunity, and a fair call, that I shall say no more, only thus much; Be ashamed of your earthly-mindedness, if you can; and be converted, or else you shall never be healed.
Here might I also aggravate your sin by its several circumstances, but I shall rather forbear; supposing that you may entertain wrong and harsh thoughts of me, though I have spoken the truth; therefore I shall at his time rather keep silence, and wish you to amend, than to rake in your sores; for thereby would your stink go more abroad in the world, Therefore I say forbear. And now to the reader, I beseech thee to have a care of thy soul, and look well to the welfare of it: And that you may do so, have a care what doctrine it is the your receivest. Be not contented until thou in deed and in truth, in the light of the Spirit of Christ, see thy sins washed away in the blood of that Lamb, who did offer up himself a ransom on the cross on Mount Calvary, for the sins of thy soul and body, together with the rest of the saints of God.
