1I mean that the heir, as long as he is a child, is no different from a slave,

 though he is the owner of everything,2but he is under guardians and managers until the date set by his father.3In the same way we also, when we were children, were enslaved to the elementary principles
 I entreat you, become as I am, for I also have become as you are. You did me no wrong. (2Co 2:5; 2Co 6:13)13You know it was because of a bodily ailment that I preached the gospel to you at first, (1Co 2:3; Ga 1:6)14and though my condition was a trial to you, you did not scorn or despise me, but received me as an angel of God, as Christ Jesus. (1Sa 29:9; Mal 2:7; Mt 10:40; 2Co 5:20)15What then has become of your blessedness? For I testify to you that, if possible, you would have gouged out your eyes and given them to me.16Have I then become your enemy by telling you the truth?

 (Ga 2:5)17They make much of you, but for no good purpose. They want to shut you out, that you may make much of them.18It is always good to be made much of for a good purpose, and not only when I am present with you, (Ga 4:13)19my little children, for whom I am again in the anguish of childbirth until Christ is formed in you! (Ro 8:10; 1Co 4:15; Phm 1:10; Jas 1:18)20I wish I could be present with you now and change my tone, for I am perplexed about you.
Example of Hagar and Sarah
21Tell me, you who desire to be under the law, do you not listen to the law?22For it is written that Abraham had two sons, one by a slave woman and one by a free woman. (Ge 16:5; Ge 21:2)23But the son of the slave was born according to the flesh, while the son of the free woman was born through promise. (Ge 17:16; Ge 18:10; Ge 18:14; Ge 21:1; Ro 9:7; Ga 4:28; Ga 4:29; Heb 11:11)24Now this may be interpreted allegorically: these women are two covenants. One is from Mount Sinai, bearing children for slavery; she is Hagar. (De 33:2; Ro 9:4)25Now Hagar is Mount Sinai in Arabia;

 she corresponds to the present Jerusalem, for she is in slavery with her children.26But the Jerusalem above is free, and she is our mother. (Heb 12:22; Re 3:12; Re 21:2; Re 21:10)27For 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.” (Isa 54:1)28Now you,

 brothers, like Isaac, are children of promise. (Ro 9:8; Ga 3:29; Ga 4:23)29But 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. (Ge 21:9; Ga 5:11)30But 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.” (Ge 21:10; Joh 8:35)31So, brothers, we are not children of the slave but of the free woman.
