Galatians 4:11

I am afraid of you, lest by any means I have bestowed labor upon you in vain. [This paragraph is addressed especially to the Gentile Christians. He reminds them that at the time of their wardship their condition differed from that of the Jews; for, having no true copy of the will or law, they were in the more severe bondage of idolatry. Having come from this low, degraded, poverty-stricken bondage into the joyous estate of sonship, where they knew and were known of God the Father, they should have been more impressed by the contrast even than were the Jews, and so should have been more reluctant to return to bondage again. They, therefore, had less excuse than the Jews, who had not been so far removed from God. The bondage is forcefully described, and the points of description are thus aptly defined by Johnson: "Weak, because they have no spiritual power to strengthen us; beggarly, because they have no rich promise like the gospel; rudiments, because they belong to a rudimentary condition, to an undeveloped state, to the childhood of the race." In proof of the unquestioned relapse of the Galatians, Paul cites their observance of days, etc., set apart by the terms of the bondage, or law. It is not stated whether these were Sabbaths and festivals of Judaism, or the ritual days of paganism, but as they were observed at the instance and through the urgency of the Judaizers, there can be little doubt that they were the former; and the Jewish calendar corresponds to Paul's list, for they had Sabbath days, and new moon festivals each month, the great feasts in their seasons, and Sabbatical years. This passage, and that in Colossians (Colossians 2:16), if taken together, show very clearly that the Christians are not required to keep the Jewish Sabbath, and Paul's closing words, expressing fear as to the results of his labors, is a forcible warning, indicating that salvation itself may be forfeited by a return to legalism.]
