Who is the Holy Spirit and What Does He Do?

Jonathan Pennington answers a question he asked as a young man and never got a clear answer to: who is the Holy Spirit and what does He do? Beginning with Ananias and Sapphira in Acts 5, he shows that the Holy Spirit is God, that He is a person with a body, a will, a voice, and emotions, and that He indwells and seals every believer. He then walks through 1 Corinthians 3:16 and 1 Corinthians 2 to explain the believer as the temple of God, the earnest of the Spirit as God's down payment guaranteeing our redemption, and how the Spirit teaches, convicts, leads, comforts, and empowers.
