Throughout the Bible the Holy Spirit is spoken of in the Bible as being God's divine power.
Exactly what is a Christian? How does the Bible define a Christian in the most accurate sense?
What does God's Holy Spirit do for us as Christians? This question goes to the heart of our religious beliefs, because without the power of God's Spirit we can have no deep, close relationship with the Father, nor can we become His children. It is because the Spirit dwells in us that we are called the children of God (Romans 8:14-17  For as many as are led by the Spirit of God, they are the sons of God.
 For ye have not received the spirit of bondage again to fear; but ye have received the Spirit of adoption, whereby we cry, Abba, Father.
 The Spirit itself beareth witness with our spirit, that we are the children of God:
 And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.
If God were a Trinity, surely the apostle Paul, who recorded much of the theological underpinnings of the early Church, would have understood and taught this understanding. Yet we find no such concept in his writings.
The story of the new Christians baptized by Philip in Samaria illustrates the importance of the ceremony of laying on of hands in the giving of the Holy Spirit.
The Bible gives us a clear answer. Paul came upon some believers in Ephesus who had been baptized by no less than John the Baptist. Yet they had not received the Holy Spirit for two reasons. One is that they did not have the laying on of hands. The other was that they apparently did not fully understand the Christian way of life, the covenant into which one enters through baptism.
Correctly understanding the scriptural truth that the Holy Spirit is God's power that can transform our lives helps us better understand His purpose and will for us.
