The Holy Spirit exalts and glorifies the Saviour. It is His office to present Christ, the purity of His righteousness, and the great salvation that we have through Him.... The Spirit of truth is the only effectual teacher of divine truth. How must God esteem the human race, since He gave His Son to die for them, and appoints His Spirit to be man’s teacher and continual guide!—Steps to Christ, 91.
Before offering Himself as the sacrificial victim, Christ sought for the most essential and complete gift to bestow upon His followers, a gift that would bring within their reach the boundless resources of grace.... Before this the Spirit had been in the world; from the very beginning of the work of redemption He had been moving upon men’s hearts. But while Christ was on earth, the disciples had desired no other helper. Not until they were deprived of His presence would they feel their need of the Spirit, and then He would come.
The Holy Spirit is Christ’s representative, but divested of the personality of humanity, and independent thereof. Cumbered with humanity, Christ could not be in every place personally. Therefore it was for their interest that He should go to the Father, and send the Spirit to be His successor on earth. No one could then have any advantage because of his location or his personal contact with Christ. By the Spirit the Saviour would be accessible to all. In this sense He would be nearer to them than if He had not ascended on high.... Wherever we are, wherever we may go, He is always at our right hand to support, sustain, uphold, and cheer.—The Desire of Ages, 668-670. WGD 20
It is through the gift of Christ that we receive every blessing. Through that gift there comes to us day by day the unfailing flow of Jehovah's goodness. Every flower, with its delicate tints and its fragrance, is given for our enjoyment through that one Gift. The sun and the moon were made by Him. There is not a star which beautifies the heavens that He did not make. Every drop of rain that falls, every ray of light shed upon our unthankful world, testifies to the love of God in Christ. Everything is supplied to us through the one unspeakable Gift, God's only-begotten Son. He was nailed to the cross that all these bounties might flow to God's workmanship. MH 424
He shall glorify me: for he shall receive of mine, and shall shew it unto you. John 16:14, KJV
