That sure the consideration of this should move all, in whom is any thing of the zeal of God, and love to souls, their own and others’, to appear in the defence of the gospel of our salvation, by all means incumbent to them, and possible for them; for if this citadel and stronghold, wherein our all, and the all of pure and true religion, lyeth, be blown up, we are gone; and indeed no less is intended by this antichristian and antievangelic enemy, than the utter subversion of true Christian religion.  Who would not then be hereby alarmed, and upon their guard, when matters are at this pass?  Should not all, who have any love to their own souls, any zeal for the glory of Christ, anointed of the Father to be our prophet, priest, and king; my desire to see the crown flourishing upon his head, and to have the gospel preserved pure and uncorrupted, be pleading with God by prayer, in the behalf of his Son’s kingdom, crown, and glory; and wrestling with him till he were pleased to dispel these clouds, and prevent this black day:  especially should they not be labouring to be acquainted, in truth and reality, with the gospel of Jesus Christ, that having the mysterious truths thereof imprinted on their souls, and their hearts cast into its mould, they may be preserved from the hurt of this deadly poison; for this, with a constant dependence upon, and use-making of Christ in all his offices, will prove the best preservative against this infection.

The persuasion whereof did induce me to publish the following heads of some sermons, after they have been translated into Dutch, and published here:  Knowing that they might be of no less use to the people of God in Britain and Ireland.  I know not a more effectual mean to unstable souls from siding with and embracing every new notion; and from being carried about with every wind of doctrine, by the slight of men, and cunning craftiness, whereby they lye in wait to deceive; than to put them upon the real exercise of gospel godliness, and to the daily practice of the main and fundamental gospel work, of living by faith in Jesus Christ, and of growing up into him, in all things, who is the head, from whom the whole body fitly joined together and compacted, by that which every joint supplieth, according to the effectual working in the measure of every part, maketh increase of the body, unto the edifying of itself in love.  Such, I am sure, as have thus learned the truth, as it is in Jesus, and are practising the same accordingly, will have an antidote within them against the strongest poison of these seducers, and a real answer to, and confutation of, all their subtile sophisms.  The soul exercising itself into gospel godliness, will find work enough to take it wholly up; and find such a solid ground to stand upon; and see such a satisfying fulness, answering all its necessities and wants, and such a sure heart-quieting ground of peace, hope, and consolation in Jesus Christ, as that it will have no leisure, and small temptation to listen to seducing perverters, and no inclination to seek after empty cisterns.
