Yet she will be saved through childbearing—if they continue in faith and love and holiness, with self-control.

1 Timothy 2:15

Interpretations differ on this verse but from considering parallel passages and well-respected commentators, I believe the verse means women will be sanctified by doing things like child-bearing and rearing. Whenever the Apostle Paul uses the word “saved” he means it in one of three senses: initial repentance and trusting in Christ, progressive sanctification or future glorification. I think in this verse, it means women will be made more like Christ when they raise and nurture children. I believe the Bible teaches that for women, good works consist of things like childbirth, breastfeeding, loving and caring for others.
