Have any Unitarians experienced the presence of the Holy Spirit, possibly in a dramatic, life-changing way, and published a testimony in which they recount their experiences?
Note: this question has been inspired by this answer.
EDIT: after some searching I was only able to find this testimony which includes experiences with the Holy Spirit and Christadelphians (one of the largest Biblical Unitarian denominations). Unfortunately, it turned out to be a testimony from a former member, so it doesn't fit the bill. If anyone is able to find a testimony along these lines from an active member, that would be fantastic.
