But you appear to be changing the tenses in the Greek. You are saying that not getting drunk with wine is evidence of having been filled with the Spirit. But the Greek here states specifically that he was referring to something needing to happen in present tense, namely that they "be filled with the Spirit."
Paul is addressing already saved believers about not being drunk with wine where there is excess, but remain filled with the Spirit as in keep the fruit of temperance which is self control thus be sober.
But the infilling of the Spirit is for much more than departing from sin. In Acts, the stated purpose is rather to be filled with supernatural power by to engage in evangelism, whereby the word is confirmed with signs and wonders following:
And He said to them, “It is not for you to know times or seasons which the Father has put in His own authority. 8 But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth.” (Acts 1:7-8)
if you apply Acts 1:7-8 to below, you may see Jesus was talking about His disciples' born again of the Spirit moment at Pentecost as promised to be sent from the Father.
John 1:12
But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: 13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but
of God.
John 14:
1Let not your heart be troubled: ye believe in God, believe also in me. 2 In my Father's house are many mansions: if it were not so, I would have told you.
I go to prepare a place for you. 3 And if I go and prepare a place for you, I will come again, and
receive you unto myself; that where I am, there ye may be also.
16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; 17 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.
John 14:25 These things have I spoken unto you, being yet present with you. 26 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.
So that was what Jesus talking about in Acts 1:7-8 for why they had to wait for the promise from the Father when He was no longer present with them but with the Father in Heaven. Pentecost was when His disciples were saved.
Jesus had explained this to Nicodemus on how and when one is born again of the Spirit and that is after His ascension which was after His crucifixion for any who believe in Him will be born again of the Spirit and thus have eternal life.
John 3:7 Marvel not that I said unto thee, Ye must be born again. 8 The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
9 Nicodemus answered and said unto him, How can these things be?
10 Jesus answered and said unto him, Art thou a master of Israel, and knowest not these things? 11 Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness. 12 If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things?
13 And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven. 14 And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:
15 That whosoever believeth in him should not perish, but have eternal life.
16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
So His disciples were saved at Pentecost as promised for all those that believe in Jesus Christ as they had received the promise of the Spirit by faith in Jesus Christ rather than by sight of Jesus Christ, so their testimony of their salvation moment is the same as every other believer that believed in Him that got saved since Pentecost.
