Hi cameo-d,
Yes the "sons of God" in the new testament are anyone who has "faith in Jesus Christ" as Galatians says.
Epistle to the Galatians:
No original of the letter is known to exist. The earliest reasonably complete version available to scholars today, named P46, dates to approximately the year 200 A.D., approximately 150 years after the original was presumably drafted.This fragmented papyrus, parts of which are missing, almost certainly contains errors introduced in the process of being copied from earlier manuscripts. [7] However, through careful research relating to paper construction, handwriting development, and the established principles of textual criticism, scholars can be rather certain about where these errors and changes appeared and what the original text probably said. [8]
Notes on Ephesians:
1:3 If the Greek is followed literally, verses 3 through 14 are a single sentence, joined together by various participles and relative clauses. Such lengthy and complex sentences are one of the clues that Paul did not write this letter. Paul’s style in the letters known to be his is much more simple and direct.
1:4-5 The selection of the elect was made “before the foundation of the world.” See also v.12. This theme of predestination occurs also in Romans 8:29-30. However, if the chosen ones were preselected by God, then there is no point in preaching the gospel in order to win converts, because such proselytizing can have no effect.
1:7 The writer declares that in Christ, the elect have “redemption through his blood.” (cf. Colossians 1:13-14.) He clearly views redemption as an accomplished fact, already achieved and enjoyed by members of the Christian community. But Jesus taught a different view of redemption. According to Jesus, redemption will occur at the second coming, when the Son of man descends on clouds from heaven with power and glory. (Luke 21:28)
Indeed, the letter to the Ephesians does not mention the return of Christ at all. In the letter to the Colossians (3:4-6), there was still an expectation that Christ would re-appear, although the expectation no longer had any immediacy to it. But now, in Ephesians, the imagery is all about salvation and redemption in the present. (In addition to 1:7, see 2:5; 2:12-13.)
