Continuing with our short series on “The Law is Not of Faith.” In the book of Galatians, Paul uses the women of Abraham (Sarah and Hagar) as illustrations while comparing the two covenants - the Old and the New. One gave birth to a child of promise (Sarah) and the other came from Mt. Sinai and gave birth to bondage. We know this is where the Mosaic law was given birth - including the Ten Commandments. It was something the Jewish people were freed from because of the child of promise. Religious doctrines which encourage us to live by the old commandments from that covenant have missed the point… we can’t live by something that is unable to bring life or righteousness to us. There is no passage that states we should abide by certain laws while others have expired. There is no exhortation in Scripture that trying to keep the commandments from the previous covenant will improve morals, reduce sin, and bring sanctification. In fact, we find the opposite within new covenant writings. We have something better in Christ: It’s called faith (and the law is not based upon faith).
Continuing on our current thread that "the law is not of faith." The Apostle Paul continues to explain and reveal the significant differences between law and faith in Galatians Chapter 4. Those who had formerly been under the law of Moses were described as slaves held in bondage. Jesus was born of a woman under that same system of law in order to redeem those who were under the law. This would result in the slaves becoming children... heirs of the promise. Paul would continue to show that most people who want to live by the law have no idea what the law says and requires (they had the impossible task of doing all of it). The child of slavery came through Hagar, symbolizing the Old Covenant at Mt. Sinai where the law was given - it gave birth to spiritual bondage. But the child of promise came through Sarah, symbolizing the freedom of grace and faith found in the New Covenant. Both Jew and Gentile believers are now children of the free woman.
In this sixth part of the series, we wrap up our brief look at Abraham and the significance of his part in God’s redemptive picture, which is a picture described throughout Scripture. Interestingly, in spite of what appears to be a fleshly effort by having a child through his servant Hagar, the Bible declares Abraham was not weak in faith, and did not waver at the promise of God through unbelief, but was strengthened in faith. Righteousness was credited to him because of belief, just as it is to us today, apart from law or works.
Hundreds of years before God gave the law to Moses, there was Abraham. Through him God brought forth a promise, where he would become the father of many nations that would occur through a child promised to him and Sarah. Abraham believed God and it was accounted to him for righteousness. It was by faith the promise arrived, not works. The Apostle Paul explains how Abraham’s two sons represent the two covenants—both the Old and the New. The son born from Hagar (the bondwoman) was born according to the flesh, whereas the son from Sarah (the freewoman) through promise. One gave birth to bondage, symbolic of Mount Sinai, and the other gave birth to freedom, which would include justification for Gentiles through faith.
