Doing my own independent research, I've noticed a clear pattern of religious people reporting feelings and sensations that they usually describe with expressions such as "waves of electricity", "fire", "heat", "burning all over", among others. I've heard expressions like these mainly from individuals in Pentecostal and Charismatic circles.
Also, here is a quote from a very descriptive testimonial posted on Charisma Magazine:
[...] In an instant, the Spirit of God gave me a single word in tongues to speak out, and as I repeated it, more words erupted through me. The power of the wonderful Holy Spirit enveloped me as what seemed like waves of electricity and what I can only describe as God's love and power washed over me. It seemed as though a spotlight exploded out of my mouth as I spoke in tongues, with my arms and hands surging with tremendous currents of electricity as the waves of power washed over the rest of my body as I loudly spoke in tongues, feeling immersed in His Spirit. [...]
Reviewing literature about these experiences in Google Scholar, I came across a paper published in 2014 by Julia L. Cassaniti and Tanya Marie Luhrmann titled The Cultural Kindling of Spiritual Experiences (https://doi.org/10.1086/677881). In this paper, the authors themselves acknowledge the existence of the phenomenon (although they attribute it to "adrenaline rushes", which I find unjustified):
The “Holy Spirit” experience, for example, is a concept often used to describe an event in which someone feelings an intense surge of power sweeping through their body like electricity, or what we would call the bodily affordance of an adrenaline rush.
These three phenomena—cataplexy, or the loss of muscle control; adrenaline surge, as if electricity is shooting through the body; and emotional surge, when someone experiences intense, overwhelming emotion—are examples of physiological phenomena that are common to all human bodies but unusual enough so that people can remember the moment independent of a specific label.
So, given the abundant reports of these dramatic spiritual experiences allegedly attributed to the Holy Spirit, is there any scriptural basis for them?
