According to theologian Rudolf Bultmann, there are two ways to think about the Holy Spirit: "animistic" and "dynamistic". In animistic thinking, it is "an independent agent, a personal power which like a demon can fall upon a man and take possession of him, enabling him or compelling him to perform manifestations of power" while in dynamistic thought it "appears as an impersonal force which fills a man like a fluid". Both kinds of thought appear in Jewish and Christian scripture, but animistic is more typical of the Old Testament whereas dynamistic is more common in the New Testament. The distinction coincides with the Holy Spirit as either a temporary or permanent gift. In the Old Testament and Jewish thought, it is primarily temporary with a specific situation or task in mind, whereas in the Christian concept the gift resides in man permanently.
