Galatians 4:5 to redeem those who were under the law, so that we might receive adoption as sons.
To redeem those under the law; The Jews are being spoken of here and Paul echos The Lord in Matthew 15:24 He answered, “I was sent only to the lost sheep of the house of Israel.” By whom are meant chiefly the Jews, who are elsewhere represented as in and under the law, in distinction from the Gentiles who were without it; (Romans 2:12) “For all who have sinned without the law will also perish without the law, and all who have sinned under the law will be judged by the law”. the Gentiles indeed, though they were not under the law of Moses, yet were not without law to God, they were under the law of nature. The law was given to Adam as a covenant of works, and not to him as a single person, but as a federal head to all mankind; hence he sinning, and they in him, they all came under its sentence of condemnation and death, God’s elect not excepted, and who are the persons said to be redeemed; for Christ was not sent to redeem all that were under the law; for as all mankind were included in it as a covenant of works made with Adam, and all are transgressors of it, the whole world is pronounced guilty before God by it, and liable to the curse of it; but not all mankind, only some out of every kindred, tongue, people, and nation. So the phrase “Those under the Law” is not the same as the “Lost sheep of Israel” in that the prior statement does pertain to the Jews, , but “those under the law includes Gentiles also, though they are Israel they are a law to themselves, and are just as guilty as the Jews before a Holy God who calls into our account. Jesus came first only to the lost sheep of Israel, and those whoo rejected His after being under the law for thousands of years are without excuse, they who have the privileges of the law, the prophets, and jewish rituals and under the tutor all these years show how depraved and sinful man heart is. He came unto His own, and His own people did not receive Him. Now they must pay the wages of their sin.
