Common experience declares how momentary and how useless are those violent fits and gusts of endeavours which proceed from fear and uncertainty, both in things spiritual and things temporal, or civil. Whilst men are under the power of actual impressions from such fears, they will convert to God, yea, they will turn in a moment, and perfect their holiness in an instant; but so soon as that impression wears off (as it will do on every occasion, and upon none at all) such persons are as dead and cold towards God as the lead or iron, which but now ran in a fiery stream, is now when the heat is departed from it.

John Owen (1616-1683) English clergyman and theologian
