Matthew Poole and continuators on Matthew 7:20

20 Wherefore by their fruits ye shall know them.

A proper effect Discovereth the Cause: Lest his Disciples should ask, how shall we distinguish True, from false Teachers? Our Saviour tells them. By their fuits you shall know them. Our Saviour sends not his Disciples to inquire into the Truth of their Mission, whether that more Internal from God, of which they could not judge, or more External from Men, who may err and send out those whom God never sent, but you shall know them (saith our Saviour) by their faithful, o[illegible: 1 letter] unfaithful Discharge of their Duty: If they be true Teachers by their discharging the Ministry, in a faithful Revelation of the Mind and Will of God, or by their Holy Life, living as ensamples to the Flock, by their Fruits of true Doctrine, and a Holy Life by the Discharge of their Ministry in good Conscience; for it is with Men, as it is with the Trees, good Trees bring forth good Fruit, corrupt Trees bring forth evil Fruit. If Men have the Root of the matter, the Seed of God abiding in them, they will in every Relation, bring forth the Fruits of Truth, and Holiness: If they have not, they will bring forth Error, and Wickedness. From whence we may learn, that our Lord expecteth from his People such a knowledge of the Scriptures, as they may be able to discern Truth from Falshood, and such a Diligence as to search the Scriptures, whether those things which their Teachers deliver to them, be according to them or no, Acts 17.11. not taking divine Truths upon Trust, nor believing any thing, because Dictated by Teachers, using their Teachers not as Dictates, but only as helpers of their Faith.
