Note 7 at Gal. 4:15: The Greek word that was translated "blessedness" is MAKARISMOS, which is a form of the word MAKARIZO that was translated as "count happy" in James 5:11. Legalism causes people to lose their joy. This is what happened to the Galatians. The NIV translates this phrase as, "What happened to all your joy?" Paul is saying, "Where is the joy you used to have through our relationship? You at one time would have done anything for me, even given me your own eyes if that were needful. But now you've drawn back. It is you that has changed, not me."

Note 8 at Gal. 4:15: As explained in note 6 at verse 13, the infirmity Paul was speaking of was not a chronic problem, but a temporary problem that was probably associated with him being stoned and left for dead. Likewise, any reference to his eyes in this verse would be related to the physical problems he suffered through this stoning.

However, it is possible that Paul does not literally mean by these statements that there was something wrong with his eyes. Just as today when someone says, "I'd give my right arm for them," that doesn't necessarily mean there is anything wrong with the other person's right arm. This is just a way of expressing an individual's commitment to another person, even to the point of sacrificing a valuable part of his own body for the benefit of the one he loves. Likewise, Paul may just be saying that these Galatians were at one time willing to do anything for Paul; what had changed?
