The dismissal of Hagar happened at Genesis 21:8-13. Paul interpreted the spiritual significance of this passage in Galatians 4:22-31.
8 The child grew and was weaned, and on the day Isaac was weaned Abraham held a great feast. 9 But Sarah saw that the son whom Hagar the Egyptian had borne to Abraham was mocking, 10 and she said to Abraham, “Get rid of that slave woman and her son, for that woman’s son will never share in the inheritance with my son Isaac.” 11 The matter distressed Abraham greatly because it concerned his son. 12 But God said to him, “Do not be so distressed about the boy and your slave woman. Listen to whatever Sarah tells you, because it is through Isaac that your offspring[a] will be reckoned. 13 I will make the son of the slave into a nation also, because he is your offspring.”
22 For it is written that Abraham had two sons, one by the slave woman and the other by the free woman. 23 His son by the slave woman was born according to the flesh, but his son by the free woman was born as the result of a divine promise. 24 These things are being taken figuratively: The women represent two covenants. One covenant is from Mount Sinai and bears children who are to be slaves: This is Hagar. 25 Now Hagar stands for Mount Sinai in Arabia and corresponds to the present city of Jerusalem, because she is in slavery with her children. 26 But the Jerusalem that is above is free, and she is our mother. 27 For it is written:
“Be glad, barren woman,
you who never bore a child;
shout for joy and cry aloud,
you who were never in labor;
because more are the children of the desolate woman
than of her who has a husband.”[a]
28 Now you, brothers and sisters, like Isaac, are children of promise. 29 At that time the son born according to the flesh persecuted the son born by the power of the Spirit. It is the same now. 30 But what does Scripture say? “Get rid of the slave woman and her son, for the slave woman’s son will never share in the inheritance with the free woman’s son.”[b] 31 Therefore, brothers and sisters, we are not children of the slave woman, but of the free woman.
In the Galatians’ passage, Paul established the typology of Sarah and Hagar. Both women represent 2 different covenants. Hagar represents the covenant made with God at Mount Sinai, that is the obey-to-be-blessed covenant. While Sarah represents the covenant made with God at Mount Zion where God swear to be God-who-remembers-no-more.
Ishmael was scoffing at Isaac when he was weaned. So Sarah told Abraham to dismiss Hagar and Ishmael. Although this upsets Abraham, God encouraged Abraham and promised to supply and bless Ishmael.
With the typology in mind, we can then interprets the dismissal as a dismissal of the first covenant when the second arrives. God has found another way to bless man. He doesn’t need to rely on man’s obedience to the law.
Has God done away with the Law? Well, He didn’t just set it aside. He had Jesus fulfilled it for all. If the covenant has been fulfilled, there is no need to keep it anymore, right? Okay, this is sounding like allowing people to sin away.
People who are concerned about sinning is concerned with behavior. I am still wondering what they are concerned about. Is it the bad effects of sin or that it is unfair to others who are behaving.
I think God is more concerned about fellowship. How can he get people to fellowship with Him. They are not coming because they are too pre-occupied with trying to get past the conditions of fellowship. So He got someone to meet all the conditions on behalf of the people. Once and for all!
Finally, it is nice to know that the benefits of fellowship with God is the abundant life and the grace-filled life. And how can that life live in sin?
