The wind
John 3:8
3:8 The wind. The only New Testament use of pneuma (meaning “spirit”) for “wind” is in this verse, although the Old Testament writers commonly used the same Hebrew word (ruach) for both “wind” and “spirit.” The reason for its unique use in this case is obviously to emphasize the similarity of the operation of the Holy Spirit to that of the wind. As the wind is invisible and gentle, so is the Spirit. And as the wind also exhibits great power on occasion, so does the Spirit (e.g., Acts 1:8).
