Out from Faith verses out from Law

Galatians 4:12-31

4.12 You become as I am, because I also am as you, brethren, I urge you. You have done me no unrighteousness. 4.13 Indeed you intuitively know that through weakness in the flesh I first brought you the good news. 4.14 And my test, the one in my body, you did not despise nor reject, but as a messenger from God you received me, as Christ Jesus. 4.15 Therefore where is your happiness? For you testify concerning me that if, assuming it were true, you had the natural ability you would have plucked out your own eyes and given them to me. 4.16 So have I, the one telling you the truth, become your enemy? 4.17 They are zealous to you, not properly, but they desire to exclude you in order that your zeal should be to them. 4.18 And it is proper to be zealous always in doing well, and not only in my presences facing you. 4.19 My children, who again I labor in birth until which Christ is metamorphosized in you. 4.20 But I wish to be present facing you now, and to change my voice, because I am at a loss among you. 4.21 Say to me, the ones desiring to be under law, do you not listen to the law? 4.22 For it is written that Abraham had two sons, one out from maidservant and one out from the free woman. 4.23 But on the one hand the one out from the maidservant was born according to the flesh, on the other hand the one out form the free woman through the promise. 4.24 This is allegorically speaking, for these women are two covenants. One, on the one hand, from Mount Sinai born into slavery, which is Hagar, 4.25 for Hagar is Mount Sinai in Arabia and corresponds to the present Jerusalem; indeed, she serves in slavery with her children. 4.26 On the other hand, the above Jerusalem is free, which is the mother of us all. 4.27 For it is written, “Rejoice, barren woman, the one not bearing children, break out and cry aloud, the one not in labor, because more are the children of the desolate than of the one having a husband”. 4.28 Indeed we, brethren, we are children of promise according to Isaac. 4.29 But just as at that time the one born according to the flesh persecuted the one according to the result of the Spirit, thus also now. 4.30 But what does the Scripture say? “Cast out the maidservant and her son, for the son of the maidservant should not inherit with the son of the free woman.” 4.31 So then, brethren, we are not children of the maidservant, but children of the free woman.
