“Have ye suffered so many things in vain? if it be yet in vain.”
King James Version (KJV)
3:4 Have ye suffered - Both from the zealous Jews and from the heathens. So many things - For adhering to the gospel. In vain - So as to lose all the blessings which ye might have obtained, by enduring to the end. If it be yet in vain - As if he had said, I hope better things, even that ye will endure to the end.
Ga 3:4 Have ye suffered so many things in vain? If they turned from the cross to the law for salvation, all that they had suffered for Christ was in vain. If [it be] yet in vain. I take this to mean, "If it be possible that you do turn to the law and make your sufferings vain".
