Just as he reminds the Galatians how they first received the Spirit, so he reminds them that that they were willing to pay a great price for their discipleship at the beginning. Some of this was seen in connection with the persecution that Paul himself had to suffer in order to preach the gospel among them.
Though he knows that none of the Lord’s chosen people can be lost, he also knows that it is by means of these warnings that God will restore them. But how can they be restored if they do not take these warnings seriously? Nevertheless he was confident that he will succeed, and though he speaks with passion, he does not speak with desperation. We are actors in God’s drama; the plot is written in advance but we must live out our parts as if all depended on us, for God has made each one the guardian of his own spiritual interests.
We must be careful when we are dealing with those who are in danger of falling away from the gospel that we do not falsely comfort them with their security in Christ. At such a time we may need to pull a veil over this doctrine, not because we do not believe it, but because it is not appropriate to hold out any hope except that based on the individual’s willing return to the Lord.
The word ‘suffered’ may also be translated ‘experienced’, in which case the reference is not to their persecutions but to all that they had experienced of the life of faith, which they were now turning their backs on.
