Reading through Chapter 3 the reader finds Paul expands on the idea of Law vs. Faith. The most important part of Chapter 3 is verses 16 – 18, with strong emphasis on 18, “For if the inheritance depends on the law, then it no longer depends on the promise, but God in His grace gave it to Abraham through a promise.” Secondary to the promise Paul reminds readers is verses 21 – 22,
“Is the law, therefore opposed to the promises of God? Absolutely not! For if a law had been given that could impart life, then righteousness would certainly have come by the law. But Scripture has locked up everything under the control of sin, so that what was promised, being given through faith in Jesus Christ, might be given to those who believe.” (Gal 3: 21-22)
Another argument this Chapter helps answer is if a believer should be baptized. There is a huge theological argument on the subject of baptism. In verse 27 it is given as example that those baptized are clothed in Christ, meaning that they show their faith outwardly by being baptized in example of faith to the world.
