"Like anal sex and BDSM, fisting is often mistakenly associated with the gay community or is considered a sex act too extreme to be appropriate for Christian couples. Not only are these views incorrect, but fisting actually has a scriptural precedent, as we will show. [...] Given the powerful symbolism of the fist, it is no surprise that couples who have partaken in the practice of fisting have described it as being a profoundly spiritual experience. On a symbolic and sexual level, a wife who is fisted by her husband has the experience of surrendering completely to the divine love and power of the Lord, as embodied by her partner's hand. The husband in turn has the experience of touching and caressing her inwardly, in such a deep and intimate manner as God touches our own souls with His grace." -- from Fisting and God's Will, on the Sex In Christ web site.
