4. Fourthly, Satan hath yet a further reach in his enticements, by _the power which he hath upon our fancies and imaginations_. That he hath such a power was discovered before. This being then supposed, how serviceable it is for his end it is now to be considered. Our fancy is as a glass, which, with admirable celerity and quickness of motion, can present before us all kinds of objects; it can in a moment run from one end of the earth to the other; and besides this, it hath a power of creating objects, and casting them into what forms and shapes it pleaseth, all which our understanding cannot avoid the sight of. Now the power of imagination is acknowledged by all to be very great, not only as working upon a melancholy and distempered spirit, of which authors give us large accounts,[185] but also upon minds more remote from such peremptory delusions; as may be daily observed in the prejudices and prepossessions of men, who by reason of the impressions of imagination, are not without difficulty drawn over to the acknowledgment of the truth of things, and the true understanding of matters; neither is the understanding only liable to a more than ordinary heat and rapture by it, but the will is also quickened and sharpened in its desires by this means. Hence is it, as one of the forecited authors observes,[186] that fancy doth often more toward a persuasion by its insinuations than a cogent argument or rational demonstration. This is no less a powerful instrument in Satan’s hand, than commonly and frequently made use of. Who amongst us doth not find and feel him dealing with us at this weapon? When he propounds an object to our lust, he doth not usually expose it naked under the hazard of dying out for want of prosecution, but presently calls in our fancy to his aid, and there raiseth a theatre, on which he acts before our minds the sin in all its ways and postures. If he put us upon revenge, or upon lusts of uncleanness, or covetousness, or ambition, we are sure, if we prevent it not, to have our imagination presenting these things to us as in lively pictures and resemblances, by which our desires may be inflamed and prepared for consent.
