Matthew Poole and continuators on 1 John 4:6

6 We are of God: He that knoweth God, heareth us; he that is not of God, heareth not us. Hereby know we the Spirit of truth, and the spirit of error .

He giveth here a further Rule whereby to judg of Doctrines and Teachers, viz. what they severally savour of, and tend to. The Doctrines and Teachers whereby these Christians were assaulted and tempted, were of an earthly Savour and Gust, tending only to gratify worldly Lusts and Inclinations, and to serve secular Interests and Designs; and therefore Men only of a worldly Spirit and Temper, were apt to listen and give entertainment to them. On the other hand, says he, (in the Name of the Asserters and Followers of true and pure Chri [illegible: 4 letters]nity, comprehended with himself) We are of God, i. e. Our Doctrine and Way proceed from God, and tend only to serve, please and glorify him, and draw all to him; therefore such as know God, i. e. are his Friends, and converse much with him, hear us; the Things we propose and offer, are grateful and savoury to them, (as Iohn 8.37▪ 47.) having manifestly no other Aim than to promote serious Godliness. And hereby may the Spirit of Truth and Error in matters of this Nature be distinguished; The one being next of Kin to Purity, and Holiness, and a godly Life; the other, to Sensuality, and a Design only of gratifying the animal Life.
