In the very first verses of the Bible the Holy Spirit is seen as involved in the creation of the universe. There we read: “In the beginning God created the heavens and the earth. Now the earth was without shape and empty, and darkness was over the surface of the watery deep, but the Spirit of God was moving over the surface of the water” (Gen 1:1-2). In another place Elihu says to Job: The Spirit of God has made me, and the breath of the Almighty gives me life (Job 33:4 cf. Gen 2:7). In fact the Hebrew word for “spirit” (ruach) can also be translated as breath or wind. The same is true in Greek (pneuma) in the Greek Old Testament and Greek New Testament. The significance of this is that breath is what gives life to a body.
In regard to the revelation of God’s word the Holy Spirit also has a role. In citing Psalm 2 Peter and John state “Master, who said by the Holy Spirit through your servant David our forefather, ‘Why do the nations rage, and the peoples plot foolish things” (Acts 4:25). Here the Psalm is said to be by the Holy Spirit though David. The human author David is described as the intermediate source of the message while the Holy Spirit is the source that channeled it to him. In citing Psalm 95, similarly the author of Hebrews states, “Therefore, as the Holy Spirit says, “Oh, that today you would listen as he speaks! (Heb 3:7). In this passage even though the Psalmist writes the message the Holy Spirit “says” it.
In the Old Testament the Holy Spirit filled individuals for various kinds of service and in some cases this filling is explicitly seen as temporary. A good example of the temporary nature of the filling of the Spirit in the Old Testament occurred in the life of Israel’s first king, Saul. The record of it starts in the book of First Samuel: “Then the spirit of God rushed upon Saul and he prophesied among them” (1 Sam10:9). But later after Saul’s disobedience to God the Spirit of God departed from him: “Now the Spirit of the Lord had turned away from [departed] Saul, and an evil spirit from the Lord tormented him” (1 Sam 16:14). Apparently, the next King of Israel, David, learned from Saul’s example. After David’s sin of adultery (and murder) with Bathsheba he recorded a prayer found in Psalm 51, “Do not reject me! Do not take your Holy Spirit away from me” (Ps 51:11). David did not want what happened to Saul happen to him. However, a temporary filling of the Spirit seen in the Old Testament era should not be confused with the baptism of the Spirit in the church age (Acts 2). This baptism is a permanent act of the indwelling of the Holy Spirit in the life of a believer. So Christians can be assured that the Holy Spirit will not be taken from them (cf. Eph 1:13-14).
