While Christ is dwelling in the heart, it is impossible to conceal the light of His presence, or for that light to grow dim. On the contrary, it will grow brighter and brighter as day by day the mists of selfishness and sin that envelop the soul are dispelled by the bright beams of the Sun of Righteousness.—Patriarchs and Prophets, 134.
Christ has promised the gift of the Holy Spirit to His church, and the promise belongs to us as much as to the first disciples. But like every other promise, it is given on conditions. There are many who believe and profess to claim the Lord’s promise; they talk about Christ and about the Holy Spirit, yet receive no benefit. They do not surrender the soul to be guided and controlled by the divine agencies.... Only to those who wait humbly upon God ... is the Spirit given.—The Desire of Ages, 672.
The promise of the Holy Spirit is not limited to any age or to any race. Christ declared that the divine influence of His Spirit was to be with His followers unto the end. From the day of Pentecost to the present time, the Comforter has been sent to all who have yielded themselves fully to the Lord and to His service. To all who have accepted Christ as a personal Saviour, the Holy Spirit has come as a counselor, sanctifier, guide, and witness. The more closely believers have walked with God, the more clearly and powerfully have they testified of their Redeemer’s love and of His saving grace.—The Acts of the Apostles, 49. WGD 336
The disciples were filled with great joy. Over and over again they repeated the words Christ had spoken to them in His last lessons, as recorded in the fourteenth, fifteenth, sixteenth, and seventeenth chapters of John; and every one had something to say about the instruction, especially with regard to the words of the fourteenth of John ...

Neither will I hide my face any more from them: for I have poured out my spirit upon the house of Israel, saith the Lord God. Ezekiel 39:29. KJV
