The Holy Spirit is the third person of the Godhead and played an important role in God's creation and plan of salvation. The Holy Spirit revealed God's word through inspiration of prophets and apostles. He confirmed the message through the apostles' preaching and gifts. The Holy Spirit convicts the world of sin and regenerates believers through obedience to the gospel. He sanctifies Christians and leads, strengthens, and comforts them as they continue in obedience.
