I didn't guarantee. Not sure what you mean by "sounds pretty Cajun."
Really? What is that word you used in post 98? I'll quote it for you, "I can all but guarantee " You've never heard the old Cajun colloquialism, "I garahntee" ?
I have read the first couple of chapters so there is no need to be condescending. It begins with:
The feeling of condescension is ALL on you my friend.
Act 1:13 And when they had entered, they went up to the upper room, where they were staying, Peter and John and James and Andrew, Philip and Thomas, Bartholomew and Matthew, James the son of Alphaeus and Simon the Zealot and Judas the son of James.
Act 1:14 All these with one accord were devoting themselves to prayer, together with the women and Mary the mother of Jesus, and his brothers.
Act 1:15 In those days Peter stood up among the brothers (the company of persons was in all about 120) and said, (ESV)
First it speaks of the whole group of them and then of the leadership of that group and the choosing of Judas' replacement. Now in Acts 2:1 there are two key words: "they" and "all."
Act 2:1 When the day of Pentecost arrived, they were all together in one place, (ESV)
That's NOT how grammar works. You go back to the last identification of they, which would be the 12. Of course if you like to practice eisegesis, you would do the gymnastics necessary to get to your POV.
The addition of "all" can change things since it is entirely unnecessary if speaking only of the 12. Without "all" it would very likely be referring to only the 12. But there really is no reason to not take Acts 2:1 as going back to verses 14 and 15 and referring to the 120, having finished the discussion of the choosing of the new Apostle.
The obvious reason ALL is used is because Jesus promised it to them. It would also ne necessary to confirm that Jesus supported the choosing of Mathias as one of the 12 in that he as well received the Holy Spirit. Jesus promised the "comforter" to his Apostles and told THEM to wait. Not the 120.
In the end it really doesn't matter. The only issue I can think of that could come of it is if someone were to use the idea that only the Apostles received the Holy Spirit to argue that then only the Apostles could impart the gift of the Holy Spirit, and therefore such died out with the last of the Apostles, putting an end to the gifts of the Spirit, including tongues.
ALL God's word matters. 2 Tim 2:15 is NOT to be ignored. Making sure we "rightly" divide the Word of truth is paramount or Paul would not have instructed it. Plenty of people alread try to deny the Holy Spirit today and on these forums. I have faith that the TRUTH in and of God's word will ALWAYS win out.
