Exalted to the right hand of God, he has received from the Father the promised Holy Spirit and has poured out what you now see and hear.
`I indeed do baptize you with water to reformation, but he who after me is coming is mightier than I, of whom I am not worthy to bear the sandals, he shall baptize you with the Holy Spirit and with fire, whose fan is in his hand, and he will thoroughly cleanse his floor, and will gather his wheat to the storehouse, but the chaff he will burn with fire unquenchable.'(Mat 3:11-12)
and others mocking said, --`They are full of sweet wine;'
and Peter having stood up with the eleven, lifted up his voice and declared to them, `Men, Jews! and all those dwelling in Jerusalem, let this be known to you, and harken to my sayings, for these are not drunken, as ye take it up, for it is the third hour of the day. `But this is that which hath been spoken through the prophet Joel: And it shall be 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 also upon My men-servants, and upon My maid-servants, in those days, I will pour out of My Spirit, and they shall prophesy;
They, therefore, indeed, having come together, were questioning him, saying, `Lord, dost thou at this time restore the reign to Israel?' and he said unto them, `It is not yours to know times or seasons that the Father did appoint in His own authority; but ye shall receive power at the coming of the Holy Spirit upon you, and ye shall be witnesses to me both in Jerusalem, and in all Judea, and Samaria, and unto the end of the earth.'
I believe Jesus had the Holy Spirit within Him even before birth(Lk 1:41), but there was clearly an anointing of the Spirit that "came upon" Him after His baptism by John. It was an anointing for ministry. I believe the "coming upon"
that the 120 experienced was this same anointing for ministry that Jesus had received at His baptism, to be multiplied in the Body at Pentecost. "You shall receive power after the Holy Spirit has come upon you and you shall be witnesses unto me...." Jesus apparently (according to Peter's declaration in the first presentation of the gospel (Ac 2:33) received the Holy Spirit in a substantially greater way after His ascension for the purpose of distributing (being the fountain head of the living waters) to believers- for the same anointing unto ministry. The result of that anointing was effective priesthood, as they were "all as one soul" and the grace of God and the word of the Lord grew and multiplied and the Lord added to the church daily such as were chosen for deliverance.
Jesus Himself taught that the Holy Spirit would come unto men in a way that had not yet occurred
"But I tell you the truth, it is to your advantage that I go away; for if I do not go away, the Helper will not come to you; but if I go, I will send Him to you. "And He, when He comes, will convict the world concerning sin and righteousness and judgment; concerning sin, because they do not believe in Me; and concerning righteousness, because I go to the Father and you no longer see Me; and concerning judgment, because the ruler of this world has been judged. "I have many more things to say to you, but you cannot bear them now. "But when He, the Spirit of truth, comes, He will guide you into all the truth; for He will not speak on His own initiative, but whatever He hears, He will speak; and He will disclose to you what is to come. "He will glorify Me, for He will take of Mine and will disclose it to you. "All things that the Father has are Mine; therefore I said that He takes of Mine and will disclose it to you.
For me, it isn't important to define all the "measures" in which the Holy Spirit has been in the world and involved in the dealings of God with men- IMO it really doesnt matter that much, it is what it is. I do think it is important that believers understand that the "coming upon" of the Spirit for the anointing to minister as sons of God is still
available and is in fact, the imperative cure for most of what ails the Body of Christ today. If Jesus needed it in order to fulfill His course, we need it as well, in order to be effective witnesses unto Him in this present evil age. I don't think it is a one time experience, but is renewed through prayer and hearing with faith. I don't think it is exclusive to any sign or gift. I think it must be maintained corporately in some measure. "The Spirit and the Bride say Come." This saying was fulfilled by the outpouring of the Spirit upon the Bride of Christ in Acts- and they came as the Lord added daily. I think it is fulfilled in the same way today. "Today if you hear His voice." As with all things spiritual- it isn't the definition but the real experience walked out with God. Being defines itself in manifestation of truth.
"And now, Lord, take note of their threats, and grant that Your bond-servants may speak Your word with all confidence, while You extend Your hand to heal, and signs and wonders take place through the name of Your holy servant Jesus." And when they had prayed, the place where they had gathered together was shaken, and they were all filled with the Holy Spirit and began to speak the word of God with boldness. And the congregation of those who believed were of one heart and soul; and not one of them claimed that anything belonging to him was his own, but all things were common property to them.
A Song of Ascents, of David.
Behold, how good and how pleasant it is
For brothers to dwell together in unity!
It is like the precious oil upon the head,
Coming down upon the beard, Even Aaron's beard,
Coming down upon the edge of his robes.
It is like the dew of Hermon
Coming down upon the mountains of Zion;
For there the LORD commanded the blessing--life forever.
