Paul clearly says that if you are a Christian, you have the Holy Spirit.
Well yes.
However many believers are told they have all that there is to have when they first believe.
Consider how many do as did Adam and Eve who ate from the tree of knowledge, when they ought to have eaten from the tree of life.
Joh 7:37 In the last day, that great day of the feast, Jesus stood and cried, saying, If any man thirst, let him come unto me, and drink.
Joh 7:38 He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water.
Perhaps some may receive at one point and not have any flow until later for some reason but throughout the book of Acts such was the receiving and outflowing following at the same time.
Pentecostals have taught that one is born again at one time and baptized in the Spirit later, but the problem with that is many only believe but have never received either and become satisfied with that.
There is no surety of salvation until one enters the Holy Place by the blood of Jesus--
1Jn 5:6 This is he that came by water and blood, even Jesus Christ; not by water only,
but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth.
The sacrifice , the golden sea, and the Holy place of the Temple is being described there as the type of Acts 2:38.
None are Christians in the true sense if they have not come to Christ in that same way. (many believers have never entered into the presence of God)
Act 2:38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
Act 2:39 For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
Act 8:5 Then Philip went down to the city of Samaria, and preached Christ unto them.
Act 8:6 And the people with one accord gave heed unto those things which Philip spake, hearing and seeing the miracles which he did.
Act 8:7 For unclean spirits, crying with loud voice, came out of many that were possessed with them: and many taken with palsies, and that were lame, were healed.
Act 8:8 And there was great joy in that city.
Act 8:12 But when they believed Philip preaching the things concerning the kingdom of God, and the name of Jesus Christ, they were baptized, both men and women.
Act 8:14 Now when the apostles which were at Jerusalem heard that Samaria had received the word of God, they sent unto them Peter and John:
Act 8:15 Who, when they were come down, prayed for them, that they might receive the Holy Ghost:
Act 8:16 (For as yet he was fallen upon none of them: only they were baptized in the name of the Lord Jesus.)
Act 8:17 Then laid they their hands on them, and they received the Holy Ghost.
Act 8:18 And when Simon
saw that through laying on of the apostles' hands
the Holy Ghost was given, ---
