God promised Sarah a child. His name was to be Isaac. So she waited. And waited. Finally she got frustrated with waiting and took matters into her own hands. Sarai offered a surrogate; her Egyptian bondwoman, Hagar. Hagar produced a son, his name was Ishmael.
Just as God promised, Sarah became pregnant and gave birth to Isaac. Now Sarah was in a pickle. Ishmael was the first born and therefore, heir. Hagar and Sarah now began bickering. The last straw? Ishmael began mocking Isaac. So Sarah asked Abraham to kick Hagar and Ishmael out.
(Don’t worry, God would bless Ishmael. However, that is a story for another time.)
Ishmael represents self effort, the Old Covenant, and the Law. By not believing in God and having faith in his promise, Sarah created a bigger mess for herself. Hagar was Egyptian and “Egypt” always represents “the world.” Also Hagar was a slave which further strengthens the concept of bondage to the law.
Isaac represents God’s promise, the New Covenant and Grace. Isaac would later become a perfect image of Christ (as he was offered as a sacrifice). Eventually Christ Himself, would come from his line. Sarah was a free woman which strengthens the concept of the freedom offered by Grace! God wanted Sarah to be the mother, not Hagar. God wanted freedom for us, not slavery.
We are not children of the bondwoman, but of the free woman! Galatians 4:21-31
Who is your mother?
May God’s Love be with you
