"Then will I sprinkle clean water upon you, and ye shall be clean: from all your filthiness, and from all your idols, will I cleanse you. A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh. And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them. And ye shall dwell in the land that I gave to your fathers; and ye shall be my people, and I will be your God."—Ezek. 36:25-28.
"And it shall come to pass afterward, that I will pour out my spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, and your young men shall see visions: and also upon the servants and upon the handmaids in those days will I pour out my spirit."—Joel 2:28, 29.
Promised through Christ. "And, behold, I send the promise of my Father upon you: but tarry ye in the city of Jerusalem, until ye be endued with power from on high."—Luke 24:49. "But whosoever drinketh of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing up into everlasting life."—John 4:14. "He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water. (But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given, because that Jesus was not yet glorified.)"—John 7:38, 39.
"If ye love me, keep my commandments. And I will pray the Father, and he shall give you another Comforter, that he may abide with you forever; even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you. At that day ye shall know that I am in my Father, and ye in me, and I in you. But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you."—John 14:15-17, 20, 26. "But when the Comforter is come, whom I will send you from the Father, even the Spirit of truth, which proceedeth from the Father, he shall testify of me."—John 15:26.
"Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you. And when he is come, he will reprove the world of sin, and of righteousness, and of judgment: of sin, because they believe not on me; of righteousness, because I go to my Father, and ye see me no more; of judgment, because the prince of this world is judged. I have yet many things to say unto you, but ye cannot bear them now. Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will show you things to come. He shall glorify me: for he shall receive of mine, and shall show it unto you. All things that the Father hath are mine: therefore said I, that he shall take of mine, and shall show it unto you."—John 16:7-15. "John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence."—Acts 1:5.
A Fulfillment of This Promise
"And when the day of Pentecost was fully come, they were all with one accord in one place. And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting. And there appeared unto them cloven tongues like as of fire, and it sat upon each of them. And they were all filled with the Holy Ghost."—Acts 2:1-4.
A Testimony of Its Fulfillment
"But this is that which was spoken by the prophet Joel; and it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams: and on my servants and on my handmaidens I will pour out in those days of my Spirit; and they shall prophesy.... This Jesus hath God raised up, whereof we all are witnesses. Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear."—Acts 2:16-18, 32, 33.
