Paul follows the law in its entirety, and secondly

Paul was so strong in his conviction that
righteousness relied solely on having faith in Jesus and trust in God, he had
the confidence to reprimand Peter when they were both in Antioch. Peter had
implicitly agreed with the position of the Judaizers on circumcision to the harm
of Gentile converts. For Peter’s hypocrisy, Paul rebuked him. In essence, the
basis of the rebuke is that adding law to grace is to destroy grace and to make
a mockery of Jesus’ life and death on the cross.                                                                                                                                         Paul’s argument of justification was
that holiness was received by faith, not by works of the law. The example of
Abraham illustrates this point exactly. And thirdly, the law, which came 430
years after God’s covenant with Abraham, cannot invalidate the promise. Jesus
was not concerned with circumcision in the slightest.           This is the heart of this epistle because Paul clearly
sets forth what justification by faith really meant and why it was true.                                                     Such vindication of
justification by faith raises a problem. “Why then was the law given at all?”
If the same God gave the promise, why would he add the law? Paul answers this
question by rationalizing that the law had a purpose to point out to the nation
of Israel its need for Christ. It was put into place to aid the people to
receive the Spirit of God when they were struggling to do so. One cannot be
spiritual by means of circumcision or just by observing the law, first of all because
no one follows the law in its entirety, and secondly because God’s blessing
cannot be earned, it is a gift. The law would not exist without the promise. Paul
goes on to validate that all believers in Christ are descendants of Abraham and
equal in the eyes of God; there are no categories for discrimination. He pities
those who observe the Sabbath and Day of Atonement before putting their trust
in Jesus, because these acts alone will never be a means of sanctification.
Paul then ponders why people agreed with him when he preached the gospel, but
not when he speaks truths about the gospel.                                                                                                After demonstrating that
the law enslaved, he points out that the Galatians, too, had experienced
slavery as pagans worshipping false gods. By accepting the Judaizers’ message,
they would simply be replacing one kind of slavery with another. Not only this,
but the outcome that the Judaizers’ message would have on the Galatians was not
only alienating them from Paul, but also robbing them of their joy in Christ. Paul
actually finds circumcision a hindrance to people’s believing in Christ. Paul
concludes his appeal employing Hagar and Sarah as an allegory for slavery and
freedom, respectively.                                                                                                             Paul then delves into how faith
should manifest in life. At stake especially is Christian liberty. Paul
addresses how enslavement of the law is detrimental to liberty. He asserts that
it enslaves the believer, turns the believer into a debtor, alienates the
believer from Christ causing him to fall from grace, hinders the progressive
sanctification of the Christian, and removes the stigma of the cross,
suggesting that Christ died for nothing. Paul explains that obsession with the
law and circumcision spread due to corrupted teaching with incorrect
information, just like a bad rumor.                                                                                                                                                      On
the other hand, Christian liberty does not give one license to do whatever he
wants. Paul wishes that believers would respect the law by keeping with the
command that sums up its purpose, “Love your neighbor as yourself.” One cannot
attain salvation if he harms other people. Bottom line is the liberty of
justification is the liberty to live for God, not the liberty to sin.
