The church of the Gentiles was not typified in Hagar, but in Sarah; from whence the scope of the apostle is to conclude, that we are not under the law, obliged to Judaical observances, but are freed from them, and are justified by faith in Christ alone, not by the works of the law. By this conclusion the apostle maketh way for the exhortation in the following chapter, pressing them to stand fast in their liberty.
