Paul's Allegorical Point

Galatians 4:22-26 NASB
22 For it is written that Abraham had two sons, one by the bondwoman and one by the free woman.
23 But the son by the bondwoman was born according to the flesh, and the son by the free woman through the promise.
24 This is allegorically speaking: for these women are two covenants, one proceeding from Mount Sinai bearing children who are to be slaves; she is Hagar.
25 Now this Hagar is Mount Sinai in Arabia, and corresponds to the present Jerusalem, for she is in slavery with her children.
26 But the Jerusalem above is free; she is our mother.

To whom do the phrases in italics refer--Hagar or Sarah?
What do we call the covenant associated with Mount Sinai?
To whom do the bolded phrases refer--Hagar or Sarah?
What covenant is associated with her?
Her child, Isaac, was the promised child, the child who would be the ancestor of the promised Seed of the Abrahamic covenant.
According to Galatians 3:16, who is that Seed?
Those who were troubling the Galatians were telling them that the Mosaic covenant had superceded the Abrahamic covenant, that's why they needed to follow the Law, not just believe in Christ's resurrection for their salvation.
So, in using this allegory about the two women, what point do you think Paul is trying to make for the Galatians? What does he want them to know?
What does Abraham's covenant with God teach us about how we are to relate to God?
Is our relationship with God something we earn?
If we're trying to earn a relationship with God, if we try to build our relationship on human effort, then whose children are we--Hagar's or Sarah's?
If we want to be Sarah's children, children of the promise, free children, then what should our relationship with God be based on?
Read Galatians 3:7.
