The Holy Spirit is one of the Persons of the Holy Trinity and is one in essence with the Father. Orthodox Christians repeatedly confess, "And I believe in the Holy Spirit, the Lord, the Giver of life, Who proceeds from the Father, Who together with the Father and the Son is Worshipped and glorified." He is called the "promise of the Father" (Acts 1:4), given by Christ as a gift to the Church, to empower the Church for service to God (Acts 1:8), to place God's love in our hearts (Romans 5:5), and to impart spiritual gifts (I Corinthians 12:7-13) and virtues (Galatians 5:22, 23) for Christian life and witness. Orthodox Christians believe the biblical promise that the Holy Spirit is given through Chrismation (anointing) at baptism (Acts 2:38). We are to grow in our experience of the Holy Spirit for the rest of our lives.
