The Holy Spirit is God, and is equal to the Father and the Son. Don't ever speak of Him as "It" or refer to Him as "an influence." He is God the Holy Spirit, and is set forth in the Bible as being distinct from the Father and the Son. In the Genesis account of creation, He is seen actively engaged in the work of creation, along with the Father and the Son. In the Old Testament, He came upon men to empower them for service; but, when they were disobedient, He departed from them.
When David sinned against the Lord, he prayed, "Do not take Thy Holy Spirit from me" (Psalm 51:11). In the New Testament, after Pentecost, we see the Holy Spirit indwelling the believer, never to leave him, filling and empowering him for service. The study of the person and work of the Holy Spirit is of utmost importance. A scriptural understanding of God the Holy Spirit will make you a better Christian and servant of God."
The Holy Spirit is a source of great comfort to Christians. He is also our Teacher and Enabler. It is wise to pray to Him as well as to our Father God and Jesus. Why not ask the Holy Spirit to fill you with Himself every day? He will make it easier to be a faithful follower of Jesus.
