But let us inquire who this bond-woman and her son really are, and what they shadow forth. Galatians iv. furnishes ample teaching as to these two points. In a word then the bond-woman represents the covenant of the law; and her son represents all who are "of works of law," or on that principle ([Greek: ex ergon nomou]). This is very plain. The bond-woman only genders to bondage, and can never bring forth a free man. How can she? The law never could give liberty, for so long as a man was alive it ruled him. (Rom. vii. 1.) I can never be free so long as I am under the dominion of any one. But while I live, the law rules me; and nothing but death can give me deliverance from its dominion. This is the blessed doctrine of Romans vii. "Wherefore, my brethren, ye also are become dead to the law by the body of Christ, that ye should be married to another, even to him that is raised from the dead, that we should bring forth fruit unto God." This is freedom; for, "If the Son shall make you free, ye shall be free indeed." (John viii. 36.) "So, then, brethren, we are not children of the bond-woman, but of the free." (Gal. iv. 31.) Now, it is in the power of this freedom that we are enabled to obey the command, "Cast out this bond-woman and her son." If I am not consciously free, I shall be seeking to attain liberty in the strangest way possible, even by keeping the bond-woman in the house; in other words, I shall be seeking to get life by keeping the law; I shall be establishing any own righteousness. No doubt, it will involve a struggle to cast out this element of bondage, for legalism is natural to our hearts. "The thing was very grievous in Abraham's sight, because of his son." Still, however grievous it may be, it is according to the divine mind that we should abidingly "stand fast in the liberty wherewith Christ hath made us free, and not be entangled again with the yoke of bondage." (Gal. v. 1.) May we, beloved reader, so fully and experimentally enter into the blessedness of God's provision for us in Christ that we may be done with all thoughts about the flesh, and all that it can be, do, or produce. There is a fulness in Christ which renders all appeal to nature utterly superfluous and vain. CHAPTER XXII.
