Jonathan Edwards on Manifestations of the Spirit

"It is a stumbling to some, that religious affections should seem to be so powerful, or that they should be so violent (as they express it) in some persons. They are therefore ready to doubt whether it can be the Spirit of God; or whether this vehemence be not rather a sign of the operation of an evil spirit. But why should such a doubt arise? What is represented in Scripture as more powerful in it's effects than the Spirit of God? Which is called the "power of the Highest" (Luke 1:35) ... So we read of the "demonstration of the Spirit and of power" (1 Corinthians 2:4) ... So the Spirit is represented by a mighty wind, and by fire, things most powerful in their operation".
