RepentCanada, I don't think so. Because in Scripture (Book of Acts) there was some kind of physical sign of knowing this. There was something that made their meeting distinct.
Because in some cases in the book of Acts the church was praying and that's it. Other's preaching and then it happened. Not every time when someone got saved is there a reference to the Baptism of the Holy Spirit.
Now, here are a few Scriptures on the difference between Salvation and Baptism of HS.
Acts 11:17 (NASB)
17 "Therefore if God gave to them the same gift as He gave to us also [b]after[/b] believing in the Lord Jesus Christ, who was I that I could stand in God's way?"
Acts 2:4 (NASB)**Keep in mind, this is [b]AFTER[/b] Peter's "positive confession" (Belief in Jesus as the Son of God)**
4 And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit was giving them utterance.
Acts 8:9-24 (NASB)[url=http://www.biblegateway.com/passage/?search=Acts%208:9-24;&version=49;]link[/url]
Key Scriptures in this:
12 But when they believed Philip preaching the good news about the kingdom of God and the name of Jesus Christ, they were being baptized, men and women alike.
13 Even Simon himself believed; and after being baptized, he continued on with Philip, and as he observed signs and great miracles taking place, he was constantly amazed.
**(These Scriptures show that they BELIEVED in Jesus as their Lord)**
14 Now when the apostles in Jerusalem heard that Samaria had received the word of God, they sent them Peter and John,
15 who came down and prayed for them that they might receive the Holy Spirit.
16 For He had not yet fallen upon any of them; they had simply been baptized in the name of the Lord Jesus.
17 Then they began laying their hands on them, and they were receiving the Holy Spirit.
**(So, AFTER their Belief in the Lord, they hadn't had the Spirit fall upon them. Showing 2 different events; or then you must support a belief of a need of 'confirmation' or laying on of the hands for regeneration. Regeneration happens at belief. Bap. in Holy Spirit happens upon earnest prayer. *Look at the ask, knock, seek examples; they are referring to the HS*)**
Acts 10:47-48 (NASB)
47 "Surely no one can refuse the water for these to be baptized who have received the Holy Spirit just as we did, can he?"
48 And he ordered them to be baptized in the name of Jesus Christ. Then they asked him to stay on for a few days.
Acts 19:2 (NASB) *(Context nails the coffin on the matter; Vs. 1-10)*
2 He said to them, [b]"Did you receive the Holy Spirit when you [u]believed?"[/b][/u] And they said to him, [u]"No,[/u] we have not even heard whether there is a Holy Spirit."
*(Believed, in what? Answer= The Lord Jesus Christ. You can't refute (maybe try) that he[Paul] is referring to something AFTER conversion.
Jesus said, "Wait for it." This is after they preached the Kingdom of God for a maximum of 3 1/2 years. Don't try to say they were unregenerate. That word 'regenerate' isn't really used in Scripture that much, so don't make a distorted doctrine out of it.
Christ referred to His second coming as 'Regeneration.' So, be careful using that term. Cause, technically, we are ALL UNREGENERED because Jesus hasn't come back yet.
