Throughout salvation history, God has been revealing Himself to us. First God the Father in the Old Testament, then Jesus Christ, God the Son, in the New Testament, then the Holy Spirit in the Church itself. How is that manifest? Where do we see or hear the Holy Spirit these days? And how will it be in heaven?
