When the Holy Spirit came upon my husband in 1993, not only he never did anything to cause that ( except there were ongoing intercession prayers for him), but also he could not control what is happening neither with his tongue nor with his body. And it took him two hours first to somehow gain control over that Spiritual storm, but for the next few weeks the manifestations were coming spontaniuosly as God wanted, again without any chance for controlling it by my husband!
