The expression “come to life” has to be understood according to context. This expression can have varying meanings in varying circumstances. For example, Paul said of his anointed fellow Christians: “It is you God made alive though you were dead in your trespasses and sins.” (Ephesians 2:1) Yes, spirit-anointed Christians were “made alive,” even in the first century, being declared righteous on the basis of their faith in Jesus’ sacrifice.-Romans 3:23, 24.
Similarly, pre-Christian were declared righteous as to friendship with God; and Abraham, Isaac, and Jacob were spoken of as “living” even though they were physically dead. (Matthew 22:31, 32; James 2:21, 23) However, they and all others who are resurrected, as well as the great crowd of faithful other sheep who survive Armageddon and any children that may be born to these in the new world, must yet be raised to human perfection. This will be accomplished by Christ and his associate kings and priests during the thousand-year Judgment Day, on the basis of Jesus’ ransom sacrifice. By the end of that Day, “the rest of the dead” will have “come to life” in the sense that they will be perfect humans free from all effects of Adamic sin. Notice that the reference to this in verse 5 occurs immediately after the preceding verse says that those who will be in heaven “came to life.” In their case it means life free from all effects of sin; they are even specially favored with immortality.-1 Corinthians 15:54.
Concerning "resurrections," there are two. One is for the anointed (Matthew 19;28; Luke 12:32; John 14:2, 3; Revelation 7:4, 13, 14; 14:1, 3; 20:6) The second are for those deemed righteous whether they are resurrected or survive the great tribulation.-John 19:16; Revelation 7:9-17.
