"He that speaketh against his own reason speaks against his own conscience, and therefore it is certain that no man serves God with a good conscience who serves him against his reason"

This quote by Jeremy Taylor recommends that it is difficult to serve God with an excellent conscience if one is going against their own factor. Taylor is suggesting that a person's conscience is carefully linked to their reason, which if one speaks versus their own reason, they are speaking against their own conscience. In other words, if one's factor tells them something, however they choose to do the opposite, they are breaking their own conscience. Taylor is recommending that it is impossible to serve God with a great conscience if one is going against their own factor. He is emphasizing the significance of listening to one's own reason and conscience when it comes to serving God. Eventually, Taylor is recommending that one ought to constantly make every effort to serve God with a great conscience, and that this can just be achieved by following one's own factor.
