The GodHead
The Godhead exists eternally in three persons: the Father, the Son, and the Holy Spirit. These three are one God, having the same nature and attributes and are worthy of the same homage, confidence, and obedience.
The Holy Spirit is also God, performing actions and possessing the attributes of the Deity. His personality is shown by the fact that He has personal characteristics and that individuals may relate to Him as a person.
Baptism in the Holy Spirit
The baptism in the Holy Spirit is an experience in which believers yield control of themselves to the Holy Spirit. Through this the believer comes to know Christ in a more intimate way and receives power to witness and grow spiritually. Believers should earnestly seek the baptism in the Holy Spirit according to the command of our Lord Jesus Christ. The initial evidence of the baptism in the Holy Spirit is speaking in other tongues as the Spirit gives utterance. This experience is distinct from and subsequent to the experience of the new birth.
Gifts of the Spirit
The gifts of the Spirit are supernatural abilities given by God through the exercising of which believers are enabled to minister effectively and directly in particular situations. They serve the dual function of building up the church and of demonstrating the presence of God within His church.
