More than any other person of the Trinity, the Holy Spirit is active in our lives, making sure that we receive forgiveness, and joy, and goodness, and strength, and peace, and all the other blessings of salvation. The Holy Spirit’s creative power in the natural world is first seen in the creation account of Genesis 1.

When you read the opening chapter of the Bible, the Spirit is hovering above the waters. When you turn to Colossians 1, we read that Christ is the Creator, and he creates by means of the Holy Spirit. [Dr. Derek Thomas]

The Holy Spirit’s creative power can also be seen through the many miracles he empowered in Scripture. For example, in the Old Testament, he enabled Moses to get water from a rock. Of course, in the New Testament, one of his greatest miracles was the incarnation, causing the virgin Mary to become pregnant with Jesus. He enabled Jesus to multiply food to feed five thousand people, he raised Jesus from the dead, and he also empowered all of Paul’s miracles and ministry. And of course, on the last day, the Holy Spirit will use his creative power to resurrect the physical bodies of all faithful Christians, giving us perfect, incorruptible bodies like the one Jesus already has.

The Holy Spirit is generally identified as the person of the Trinity who is the agent of revelation, testimony and understanding.

We, all of us, need the illumination of the Spirit because we, all of us, are spiritually blind without it. God who commanded the light to shine out of darkness — that’s back in creation, of course — has shone in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ. That’s the illumination of the Spirit. [Dr. J. I. Packer]

Scripture teaches that human beings are born in a state of spiritual death. So, in order to save us from this predicament, the Holy Spirit creates new life in us by making our spirits live before God. The Bible talks about this new life in terms of “regeneration “and “being born again.” After we are regenerated, the Holy Spirit continues to work in us to change our thoughts, feelings and actions, in order to make us the kind of people that love and obey the Lord. All these changes in our character result from the active, creative power of the Holy Spirit as he conforms us to the image of Jesus Christ.

The blessings we receive as a result of the Holy Spirit’s administration of saving grace are already reserved for us on the basis of Jesus’ work. But we do not begin to receive their benefits until the Holy Spirit applies them to us. Now, all Christians agree that the Holy Spirit gives supernatural gifts to his church. Gifted individuals might benefit from their own gifts. But the primary goal and focus of gifting is the benefit of the church. They are creative works of power that the Holy Spirit uses to build up his church as a whole.

One benefit of having a rich understanding of the Spirit’s work is just to know that God works with us in a very personal way. So, the Spirit actually dwells in our hearts. He prays with us and for us. He gives us gifts of holiness, and he gets involved with us in so many ways. In fact, in every phase of our life he gives us the fruits of Christian virtues as Paul says in Galatians. He gives us many gifts for service in the church and all of this is God’s work with us through the Spirit. [Dr. John M. Frame]
