Natural Impulses Are Not Spiritual Guidance

It is sometimes the case, that persons act from certain interior impressions, which may properly be termed IMPULSES. It would certainly be very injurious to the cause of holiness, if the doctrine should prevail, that mere interior impressions or impulses may of themselves become the rule of conduct to a holy person. That persons in sanctification are under a divine guidance, and that they cannot retain the grace of sanctification without such guidance, is entirely true. But it has sometimes been the case, that men have mistaken natural impulses for the secret inspirations of the Spirit; and in the flattering belief of being guided by a higher power, have experienced no other guidance than that of their own rebellious passions. On the danger of such a state, of which the church has seen too many melancholy instances, it is unnecessary to remark.
