“You have always presumed on my forbearance,” Stannis
Sarah, the Church, as the bride of Christ bears free children who are not subject to the Law.
VERSE 27. For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband.
Paul quotes the allegorical prophecy of Isaiah to the effect that the mother of many children must die desolately, while the barren woman shall have an abundance of children. (Isaiah 54:1.) He applies this prophecy to Hagar and Sarah, to the Law and the Gospel. The Law as the husband of the fruitful woman procreates many children. For men of all ages have had the idea that they are right when they follow after the Law and outwardly perform its requirements.
Although the Law has many children, they are not free. They are slaves. As servants they cannot have a share in the inheritance, but are driven from the house as Ishmael was cast out of the house of Abraham. In fact the servants of the Law are even now barred from the kingdom of light and liberty, for "he that believeth not, is condemned already." (John 3:18.) As the servants of the Law they remain under the curse of the Law, under sin and death, under the power of the devil, and under the wrath and judgment of God.
On the other hand, Sarah, the free Church, seems barren. The Gospel of the Cross which the Church proclaims does not have the appeal that the Law has for men, and therefore it does not find many adherents. The Church does not look prosperous. Unbelievers have always predicted the death of the Church. The Jews were quite certain that the Church would not long endure. They said to Paul: "As concerning this sect, we know that everywhere it is spoken against." (Acts 28:22.) No matter how barren and forsaken, how weak and desolate the Church may seem, she alone is really fruitful before God. By the Gospel she procreates an infinite number of children that are free heirs of everlasting life.
The Law, "the old husband," is really dead. But not all people know it, or want to know it. They labor and bear the burden and the heat of the day, and bring forth many children, children that are bastards like themselves, children born to be put out of the house like Ishmael to perish forever. Accursed be that doctrine, life, and religion which endeavors to obtain righteousness before God by the Law and its creeds.
The scholastics think that the judicial and ceremonial laws of Moses were abolished by the coming of Christ, but not the moral law. They are blind. When Paul declares that we are delivered from the curse of the Law he means the whole Law, particularly the moral law which more than the other laws accuses, curses, and condemns the conscience. The Ten Commandments have no right to condemn that conscience in which Jesus dwells, for Jesus has taken from the Ten Commandments the right and power to curse us.
Not as if the conscience is now insensitive to the terrors of the Law, but the Law cannot drive the conscience to despair. "There is now no condemnation to them which are in Christ Jesus." (Romans 8:1.) "If the Son shall make you free, ye shall be free indeed." (John 8:36.)
