Gal 5:18 and 22 together show that Paul's mentality was totally different than his previous life in Judaism.
Galatians 5:18 includes a condition, an "if". For the Holy Spirit doesn't take away the free will of saved people (1 Thessalonians 5:19). They can wrongly employ their free will to commit sin without repentance, to the ultimate loss of their salvation (Hebrews 10:26-29; 1 Corinthians 9:27, Matthew 7:22-23).

The fruit grows because the Spirit is at work through the love of God in the Gospel (2:20).
Initial salvation by grace through faith without works (Ephesians 2:8-9, Titus 3:5, Romans 4:1-5) doesn't automatically produce good works. That's why saved people must be careful to maintain good works (Titus 3:8), and why it's possible for saved people to wrongly employ their free will to become utterly lazy without repentance, to the ultimate loss of their salvation (Matthew 25:26,30, John 15:2a, Romans 2:6-8).
2 Corinthians 5:9, 1 Corinthians 3:9, Colossians 1:29, and Philippians 2:12b show that Christians themselves must actually labor, along with God.

By saying it that way, he has just closed the argument he opened at 3:3 when he faulted them for continuing (as C'ians!) by human effort.
"This only would I learn of you, Received ye the Spirit by the works of the law, or by the hearing of faith? Are ye so foolish? having begun in the Spirit, are ye now made perfect by the flesh?" (Galatians 3:2-3).
Galatians 3:2-3 means that the works of the letter of the Old Covenant Mosaic law, especially its physical circumcision (Galatians 6:12-13), are works of the flesh, as opposed to spiritual works of faith (Philippians 3:2-14; 1 Thessalonians 1:3, Galatians 5:6, Titus 3:8). For the letter of the Old Covenant Mosaic law isn't of faith (Galatians 3:12). Also, compare Romans 7:5-6.
Galatians 3:2-3 means that works of the letter of the Old Covenant Mosaic law, works of the flesh/not faith (Galatians 3:12), can't make believers perfect.
Galatians 3:2-3 isn't contradicting the fact that initially saved people must have both faith and continued works of faith (1 Thessalonians 1:3, Galatians 5:6b, Titus 3:8) (not works of the letter of the Old Covenant Mosaic law), if they're to obtain ultimate salvation (Romans 2:6-8, James 2:24, Matthew 7:21, Matthew 25:26,30, Philippians 2:12b, Philippians 3:11-14; 2 Corinthians 5:9, Hebrews 5:9, Hebrews 6:10-12; 2 Peter 1:10-11, John 15:2a). For believers must actually continue to do righteous deeds if they're to continue to be righteous (1 John 3:7, James 2:24,26). And there's no assurance that believers will choose to do that, instead of wrongly employing their free will to become utterly lazy without repentance, to the ultimate loss of their salvation (Matthew 25:26,30, John 15:2a).

the genetic Jews are and always will be a different 'ethnos' than any other, but that is not the group God works with anymore.
That's right insofar as while all genetic Jews are part of genetic Israel (Romans 9:3-5), being part of the true, spiritual Israel, the true, spiritual seed of Abraham, the promised seed, isn't based on genetics (Romans 9:6-24), but on God's election (Romans 9:11), which includes both some Jews and some Gentiles (Romans 9:24).
All believing Jews and all believing Gentiles are part of the true Israel (Ephesians 2:12,19, Romans 11:17,24, Revelation 21:9,12; 1 Peter 2:9-10, John 10:16), the seed of Abraham (Galatians 3:28-29, Romans 4:16-17), the promised seed, just as Isaac was (Galatians 4:28). And so all Gentiles in the church, along with all Jews in the church, are heirs of all the promises made by God to Israel (Ephesians 3:6, Ephesians 2:12,19, Galatians 3:29, Romans 15:27).
In Romans 9:8, by "the children of the flesh", Paul means genetic Jews, who are the genetic children of Abraham (Romans 11:1, Acts 13:26, John 8:37). And by "the children of God"/"the children of the promise", Paul means the elect, both some Jews and some Gentiles (Romans 9:24, Galatians 4:28). Romans 9:6-8 means that not all Jews are elect (John 8:37-47, John 10:26) and that some Gentiles are elect (Romans 9:24, John 10:16, John 11:52). Only a remnant of genetic Israel is elect (Romans 9:27).

God's Israel believes, no matter what 'ethnos' they are. They believe on the Gospel event for their justification from their sins. Those who believe otherwise are not Israel.
Some non-believing, genetic Israelites are still considered by God to be Israel insofar as they're elect (Romans 11:25,28). All the elect, non-believing, genetic Israelites who don't become believers before Jesus' second coming will become believers (and so will become members of the church: Ephesians 4:4-6) at the second coming (Romans 11:26), when they see the returned Jesus in person (Zechariah 12:10-14).

This shifts all the OT prophecies as the NT shows over and over (for ex., Acts 15's use of Amos 9).
Acts 15:14-17 doesn't say or mean that Amos 9:11-12 is "fulfilled", only that the basic principle of the salvation of Gentiles "agrees" (Greek "sumphoneo", G4856) with the idea of Amos 9:11-12, and only as it was understood by the (fallible) individual quoted in Acts 15:14-17. A different way of understanding Amos 9:11-12 is by looking at the original Hebrew: Amos 9:11-12 can mean that the house of David will be restored to power and will possess Edom (present-day southern Jordan) and all other nations. This will be fulfilled during the coming millennium, which won't occur until after Jesus' 2nd coming (Revelation 19:7 to 20:6, Zechariah 14:3-21). Jesus is of the house of David (Luke 1:69, Matthew 1:1), and so at his return he will restore the house of David to power by sitting on the throne of David (Luke 1:32, Isaiah 9:7, Isaiah 16:5) and ruling the earth (Zechariah 14:9, Psalms 72:8-11).
