Have ye suffered so many things in vain?
&c.] These Galatians had suffered great reproach, many afflictions and persecutions for the sake of the Gospel, as all that embrace it must expect to do; and which to them that persevere in the faith of the Gospel will not be in vain, they will be followed with eternal life and glory; not that these things are meritorious of such happiness, or deserve such a reward; the reward of them is not of debt, but of grace. But, if such who have made a profession, and have suffered for it, should after all relinquish it, their sufferings for it are in vain; they will come short of that glory which is promised to them that suffer for righteousness sake: and this is another aggravation of the folly of these persons, that they should suffer so much persecution for the Gospel, which, if not true, they must have suffered in vain, and might as well have avoided it; and, if true, by relinquishing it not only sustain a great loss, but bring great hurt and damage to themselves:
if it be yet in vain;
by which words the apostle does, as it were, correct himself, and expresses his hope of them, that they would see their mistake, revoke their error, and abide by the truth of the Gospel.
