Commentaries:
The Holy Spirit is the power of God—not a personage, entity, consciousness, or part of the Godhead or a trinity. The Bible speaks of the Spirit as the power or mind of God, the power of love and of a sound mind. It emanates from Him and thus can be said to be "poured out" (Titus 3:5-6), "breathed" (John 20:22), and used to "fill" (Acts 2:4) and "anoint" (Acts 10:38).

The Holy Spirit
The Knox translation of the Bible renders this, "Then You send forth Your spirit and there is fresh creation." The Holy Spirit is the means, the channel, through which God's creative energy or power is manifested. Here, it is portrayed strictly in a physical application. However, if God did not send forth His Spirit, there would have been neither "a creation" nor a "renewing." If God had not sent forth His Spirit, either earth would never have appeared, or it would have remained in a state of destruction.

Pentecost and the Holy Spirit
God originally created the earth with such perfection and beauty that the angels shouted with joy! Our Creator does all things in an organized manner and completes all His works in exquisite splendor. But the earth had somehow become formless and chaotic so that God had to refashion it before man could be created.
