Galatians 3:4

Did ye suffer so many things in vain? If it be indeed vain. [Paul here reproves them in that they have begun their life in the manhood of the Spirit, with the attendant spiritual powers, liberties and graces, and were now seeking to advance or perfect that life by turning back to the childhood of the law with its fleshly forms, rites and ordinances. They were advancing backward! (See Galatians 4:1-6) He next reminds them of their sufferings, which were vain, since they might have escaped them altogether, had they begun by embracing Judaism, for the Jews were not being persecuted, but were the very parties who had stirred up the hostility of the Gentiles against all Christians. "If it be indeed vain," as translated in the text, expresses a hope that they may repent of their apostasy, and so not lose the reward of their sufferings (Matthew 5:11-12). But the phrase may be rendered "if indeed it is only in vain," which expresses a desire that the loss may be confined to the reward of their sufferings, and may not be extended to something further, as the loss of their salvation. Cook, Meyer, etc., prefer this latter meaning, but, though less commonplace and more forceful, it is also more strained.]
