There is neither Jew nor Greek, slave nor free, male nor female, for you are all one in Christ Jesus. (Galatians 3:28 BSB)
Some people claim that this verse supports the Woke Left's genderless agenda. Actually this is not true. This verse affirms that race, class and gender exist.
Galatians 3:28 affirms that race exist, but it is not a hindrance to salvation.
Galatians 3:28 affirms that class exist, but it is not a hindrance to salvation.
Galatians 3:28 affirms that gender exist, but it is not a hindrance to salvation.
During the coming millennium, race, class and gender will still exist. I am very sure that male and female will still exist in the coming millennium. The nations (other than the Israelites) will still exist as distinct races during the millennium.
Then all the survivors from the nations that came against Jerusalem will go up year after year to worship the King, the LORD of Hosts, and to celebrate the Feast of Tabernacles. (Zechariah 14:16 BSB)
As for classes, I can see at least three distinct classes. Jesus as God and King, Priest and Prophet, will be in a class of His own. Then we have another class, which will be the saints who will be resurrected with spiritual bodies at the last trumpet and ruling with King Jesus during the millennium. The final class will be the normal people who survived the great tribulation with their natural bodies to populate the millennium kingdom.
It is sown a natural body; it is raised a spiritual body. If there is a natural body, there is also a spiritual body. (1 Corinthians 15:44 BSB)
