On Pentecost in Acts 2, God’s children were immersed into His Holy Spirit, with many more later. We think of Pentecost every time we think of receiving the Holy Spirit. What exactly is God’s Holy Spirit? Is it the third person of the Trinity? Or is Holy Spirit just God’s power, or is God’s spirit separate from Him? Or is there much more to it? But why so often is Holy Spirit described as having personality? Is the Holy Spirit an “it” – or much more? WHY does scripture say, “the Lord is the Spirit” – 2 Cor. 3:17.
