Galatians 4:12-31 - Confirming Justification By Faith

Galatians 4:12-31 Discussion Questions
1) In verses 16-18 is Paul preaching against having zeal and passion?

2) Does God want us to use the Old Testament Stories by way of allegory to inform us about Himself? If so, how?

3) If Hagar represent Mt Sinai and the Mosaic Law, self-effort and bondage, then what does Sarai represent?

4) The "Working Marthas" will always find a reason to get mad at whom? (Think of the time that Jesus came to Martha's house)
