21 Tell me, you who desire to be under the law, do you not listen to the law? 22 For it is written that Abraham had two sons, one by a slave woman and one by a free woman. 23 But the son of the slave was born according to the flesh, while the son of the free woman was born through promise. 24 Now this may be interpreted allegorically: these women are two covenants. One is from Mount Sinai, bearing children for slavery; she is Hagar. 25 Now Hagar is Mount Sinai in Arabia; she corresponds to the present Jerusalem, for she is in slavery with her children. 26 But the Jerusalem above is free, and she is our mother. 27 For it is written,
“Rejoice, O barren one who does not bear;
break forth and cry aloud, you who are not in labor!
For the children of the desolate one will be more
than those of the one who has a husband.”
28 Now you, brothers, like Isaac, are children of promise. 29 But just as at that time he who was born according to the flesh persecuted him who was born according to the Spirit, so also it is now. 30 But what does the Scripture say? “Cast out the slave woman and her son, for the son of the slave woman shall not inherit with the son of the free woman.” 31 So, brothers, we are not children of the slave but of the free woman. – Galatians 4:21-31 ESV
The Old Testament and the New Testament represent two covenants made by God with His people. Paul uses the two wives of Abraham and their two sons to serve as illustrations of the differences between these two covenants. Hagar was actually the handmaiden to Sarah, Abraham's wife. When years passed, and Sarah still found herself barren and unable to bear a son for Abraham, she came up with the bright idea to give her handmaiden to Abraham so that he might have a son through her. This was her attempt to help God out, and Abraham willingly and eagerly agreed to the plan.
The result? Abraham produced a son with Hagar, whose name was Ishmael. Paul makes it clear that "the son of the slave wife was born in a human attempt to bring about the fulfillment of God's promise" (Galatians 4:23 NLT). God had promised to make Abraham fruitful and provide him with more descendants than he could possibly count.
“I will make of you a great nation, and I will bless you and make your name great, so that you will be a blessing. I will bless those who bless you, and him who dishonors you I will curse, and in you all the families of the earth shall be blessed.” – Genesis 12:2-3 ESV
“I have made you the father of a multitude of nations. I will make you exceedingly fruitful, and I will make you into nations, and kings shall come from you. And I will establish my covenant between me and you and your offspring after you throughout their generations for an everlasting covenant, to be God to you and to your offspring after you.” – Genesis 17:5-7 ESV
But at the point when Sarah came up with her plan to use Hagar as a surrogate, she and Abraham still had no son. The promise of God had not yet been fulfilled, which prompted her to come up with an alternative plan. When God's promise appeared to have bogged down, Abraham and Sarah decided to step in and fulfill the promise of God on their time frame. Ishmael was the child born by human effort.
But God did not need any help when it came to fulfilling His promise. He simply had a different timeline. He refused to accept Ishmael as the substitute, despite the pleadings of Abraham. This was not the first time that Abraham had tried to convince God to accept a different plan for fulfilling the promise. Long before Ishmael was born, Abraham had begged God to allow his manservant to serve as his heir.
“O LORD God, what will you give me, for I continue childless, and the heir of my house is Eliezer of Damascus?” 3 And Abram said, “Behold, you have given me no offspring, and a member of my household will be my heir.” – Genesis 15:2-3 ESV
But that was not God’s plan, and He informed Abraham that His promise would be fulfilled in His way.
“This man shall not be your heir; your very own son shall be your heir.” And he brought him outside and said, “Look toward heaven, and number the stars, if you are able to number them.” Then he said to him, “So shall your offspring be.” And he believed the LORD, and he counted it to him as righteousness. – Genesis 15:4-6 ESV
It’s interesting to note that the very next chapter of Genesis contains the story of Sarah’s plan to use Hagar as a means to an end, and Abraham agreed to it. Despite his professed belief in God’s promise, he bought into his wife’s Plan B and produced a son without God’s approval and, therefore, outside of God’s will. Yet, chapter 17 contains God’s covenant commitment to fulfill the promise He made to Abraham.
“As for Sarai your wife, you shall not call her name Sarai, but Sarah shall be her name. I will bless her, and moreover, I will give you a son by her. I will bless her, and she shall become nations; kings of peoples shall come from her.” – Genesis 17:15-16 ESV
In the course of time, God gave Abraham a son through Sarah, even though she was quite old and barren. God fulfilled His promise in His time and on His terms. Isaac would become the child of the promise. He would be the means by which God fulfilled the covenant commitment He had made to Abraham.
Paul uses these two women to illustrate the differences between the two covenants. Hagar would come to represent the law by illustrating life lived by human effort. Her son was the result of human effort and planning, but he was not the fulfillment of God's promise. His birth could not substitute for God's promise.
As Ishmael and Isaac grew older, Ishmael would persecute Isaac out of jealousy. He knew that he was not the heir, even though he was the firstborn. Ishmael could not understand why he was not accepted as the rightful heir to Abraham’s inheritance. After all, he was Abraham’s flesh and blood just as Isaac was.
But Paul uses Ishmael’s predicament to illustrate the actions of the Jews in his day. He states that those who live according to the law were still persecuting the rightful heirs of God. The believers to whom Paul was writing were "children of the promise just like Isaac" (Galatians 4:28 NLT). They were children of God born by the power of the Spirit of God. But those trapped under the law were persecuting them, attempting to force them to earn their rightful place in God's family through human effort. Paul reminds them, "dear brothers and sisters, we are not children of the slave woman; we are children of the free woman" (Galatians 4:31 NLT). We are free. We are heirs. We are beneficiaries of the promise of God as a result of the efforts of God alone.
Like Isaac, who was born by the miracle and power of God, we have been born again by the grace and mercy of God made possible by the work of Jesus Christ on the cross. None of it was due to our effort. We did not earn it or deserve it. This was a persistent and consistent message in virtually all of Paul’s letters.
God saved you by his grace when you believed. And you can’t take credit for this; it is a gift from God. Salvation is not a reward for the good things we have done, so none of us can boast about it. – Ephesians 2:8-9 NLT
…he saved us, not because of the righteous things we had done, but because of his mercy. He washed away our sins, giving us a new birth and new life through the Holy Spirit. He generously poured out the Spirit upon us through Jesus Christ our Savior. Because of his grace he made us right in his sight and gave us confidence that we will inherit eternal life. – Titus 3:5-7 NLT
For God saved us and called us to live a holy life. He did this, not because we deserved it, but because that was his plan from before the beginning of time—to show us his grace through Christ Jesus. – 2 Timothy 1:9 NLT
God alone saves. We can't save ourselves, and we can't sanctify ourselves. Human effort plays no part in God's redemptive plan for man. It is His promise, and it will be fulfilled according to His terms and through His power alone.
Father, thank You for this reminder that my effort is unnecessary. I don't have to try to earn Your favor through my own energy. But so often I try to come up with ways to help You out. I try to step in and do what I seem to think You are incapable of doing. But Your promise doesn't need my help. It is all based on You and You alone. My position as Your child has nothing to do with my worth or my works. It is all Your doing. Amen.
