Question: How exactly is the women saved from child birth? Or is the question, what are you saved from?
Answer: There is not an easy answer to what this verse means. There are a few possible meanings, here are the two that I think are the best options.
1. Paul could be saying that she is saved in THE childbirth, that is the birth of Jesus. The idea being that she was deceived in the garden, but she also brought the Savior to mankind.
2. The word 'saved' can also mean 'made well, or whole'. Paul could be saying that she is made whole, or fulfilled in childbearing. The idea being that she will find her greatest fulfillment in her role in the home, not in a role in the church.
