3. They come, secondly, with an appearance of usefulness. Indeed to this, to do good they are particularly called. They are set apart for this very thing. They are particularly commissioned, to watch over your soul and to train you up to eternal life. ’Tis their whole business, to _go about doing good, and healing those that are oppressed of the devil_. And you have been always accustomed to look upon them in this light, as messengers of God, sent to bring you a blessing. 4. They come, thirdly, with an appearance of religion. All they do, is for conscience sake! They assure you, it is out of mere zeal for God, that they are making God a liar. It is out of pure concern for religion, that they would destroy it, root and branch. All they speak, is only from a love of truth, and a fear lest it should suffer. And, it may be, from a regard for the church, and a desire to defend her from all her enemies. 5. Above all, they come with an appearance of love. They take all these pains, only for _your_ good. They should not trouble themselves about you, but that they have a kindness for you. They will make large professions of their good-will, of their concern for the danger you are in, and of their earnest desire, to preserve you from error, from being intangled in new and mischievous doctrines. They should be very sorry to see one who _means_ so well, hurried into any extreme, perplext with strange and unintelligible notions, or deluded into enthusiasm. Therefore it is, that they advise you, to keep still, in the plain middle way: and to beware of _being righteous overmuch_, lest you should _destroy yourself_. III. 1. But how may we know, what they really are, notwithstanding their fair appearance? This was the third thing into which it was proposed to inquire. Our blessed Lord saw how needful it was for all men to know _false prophets_, however disguised. He saw likewise, how unable most men were, to deduce a truth thro’ a long train of consequences. He therefore gives us a short and plain rule, easy to be understood by men of the meanest capacities, and easy to be applied upon all occasions. _Ye shall know them by their fruits._ 2. Upon all occasions you may easily apply this rule. In order to know whether any who speak in the name of God, are false or true prophets, it is easy to observe, first, What are the fruits of their doctrine, as to themselves? What effect has it had upon their lives? Are they holy and unblamable in all things? What effect has it had upon their hearts? Does it appear by the general tenor of their conversation that their tempers are holy, heavenly, divine? That the mind is in them which was in Christ Jesus? That they are meek, lowly, patient lovers of God and man, and zealous of good works?
