What is this Holy Spirit who was poured out so miraculously upon the disciples of Jesus, and who gathered so glorious a congregation from among the Jews? Is this Holy Spirit some spiritual state and power of the human mind, wrought and effected by God? When it is said that the Holy Spirit was poured out, and that He did these wonderful things, does this merely mean that God wrought and effected such marvellous things? No. The Holy Spirit is God, the living and personal God Himself. Scripture says that they in whom the Spirit of God, the Holy Ghost, dwells, are the temple of God.(1 Cor. 3:16) Hence the Holy Spirit is God. But again, Jesus said to His disciples in the night before His death: "The Holy Spirit, whom the Father will send you in My name, He shall teach you all things." If the Father sends the Holy Spirit in the name of the Son, then, evidently, the Holy Spirit, who is God, is not the same person as the Father and the Son. And aren't we baptised "in the name of the Father and of the Son and of the Holy Spirit"? The Holy Spirit is the third person of the Holy Trinity, true God with the Father and the Son. He is the gracious and merciful God who through the Gospel calls us poor miserable sinners to Christ, and enlightens us, so that we believe in our Saviour and come to Him, and are saved; and with great long-suffering He sanctifies and keeps us in the true faith to our end. To this end the Father sends Him in the name of the Son, who has reconciled us to Him and re-established the communion between God and us. The Holy Spirit teaches us to believe in Christ, our Saviour, and so to become God's dear children, whom God will take to heaven. O Christian, know, honour, praise, and love the Holy Spirit, and abide with His Word, by means of which He keeps you in true faith and brings you to heaven.
