Galatians 3 is the template, the “devil” always tries to muddy the details. The handling of sins is another issue covered by other passages of the Bible but yes...if sins are repented of and forgiven, then the past must not be used as a weapon to knock people down since Christ has forgiven them and especially as they have remained penitent and walking in faith! In Christ, there is no separate race, no rich no poor, no slave or free! We are all spiritual heirs of Abraham and to the grace of God! Notice it also says “no man or woman” as well which harkens back to what Christ says about the lack of marriage or the need of it between men and women in the day of the Resurrection of the saints of God! Now while we exist in this present age, yes there are still stipulations on the roles of men and women in the church but ultimately they are just differences in function...not differences in spiritual equality! In that sense, God sees men and women as equal in terms of worth and value in his sight! We have no idea what a wonder it will be to see women, fully expressed as such in the day of the Resurrection...they will be totally awesome to behold!
Oh AMEN!
