I. How the people are deceived by the false prophets. Those flatterers seduce them, saying, Peace, and there was no peace, v. 10. They pretended to have seen visions of peace, v. 16. But that could not be, for there was no peace, saith the Lord God. There was no prosperity designed for them, and therefore there could be no ground for their security; yet they told them that God was at peace with them, and had mercy in reserve for them, and that the war they were engaged in with the Chaldeans should soon end in an honourable peace, and their land should enjoy a happy repose and tranquillity. They told the idolaters and other sinners that there was neither harm nor danger in the way they were in. Thus they seduced God's people; they put a cheat upon them, led them into mistakes, and drew them aside out of that way of repentance and reformation which the other prophets were endeavouring to bring them into. Note, Those are the most dangerous seducers who suggest to sinners that which tends to lessen their dread of sin and their fear of God. Now this is compared to the building of a slight rotten wall, or, according to our Saviour's similitude, which is to the same purport with this (Matt. vii. 26), the building of a house upon the sand, which seems to be a shelter and protection for a while, but will fall when a storm comes. One false prophet built the wall, set up the notion that God was not at all displeased with Jerusalem, but that the city should be confirmed in its flourishing state, and be victorious over the powers that now threatened it. This notion was very pleasing, and he that started it made himself very acceptable by it and was caressed by every body, which invited others to say the same. They made the matter look yet more plausible and promising; they daubed the wall, which the first had built, but it was with untempered mortar, sorry stuff, that will not bind nor hold the bricks together; they had no ground for what they said, nor had it any consistency with itself, but was like ropes of sand. They did not strengthen the wall, were in no care to make it firm, to see that they went upon sure grounds; they only daubed it to hide the cracks and make it look well to the eye. And the wall thus built, when it comes to any stress, much more to any distress, will bulge and totter, and come down by degrees. Note, Doctrines that are groundless, though ever so grateful, that are not built upon a scripture foundation nor fastened with a scripture cement, though ever so plausible, ever so pleasing, are not of any worth, nor will stand men in any stead; and those hopes of peace and happiness which are not warranted by the word of God will but cheat men, like a wall that is well daubed indeed, but ill-built.
