Галатам 4:18

good to be zealously affected--rather, to correspond to "zealously court" in Gal 4:18, "to be zealously courted." I do not find fault with them for zealously courting you, nor with you for being zealously courted: provided it be "in a good cause" (translate so), "it is a good thing" (Co1 9:20-23). My reason for saying the "not well" (Gal 4:17; the Greek is the same as that for "good," and "in a good cause," in Gal 4:28), is that their zealous courting of you is not in a good cause. The older interpreters, however, support English Version (compare Gal 1:14). always--Translate and arrange the words thus, "At all times, and not only when I am present with you." I do not desire that I exclusively should have the privilege of zealously courting you. Others may do so in my absence with my full approval, if only it be in a good cause, and if Christ be faithfully preached (Phi 1:15-18).

The apostle, in this chapter, is still carrying on the same general design as in the former - to recover these Christians from the impressions made upon them by the judaizing teachers, and to represent their weakness and folly in suffering themselves to be drawn away from the gospel doctrine of justification, and to be deprived of their freedom from the bondage of the law of Moses. For this purpose he makes use of various considerations; such as, I. The great excellence of the gospel state above the legal (Gal 4:1-7). II. The happy change that was made in them at their conversion (Gal 4:8-11). III. The affection they had had for him and his ministry (Gal 4:12-16). IV. The character of the false teachers by whom they had been perverted (Gal 4:17, Gal 4:18). V. The very tender affection he had for them (Gal 4:19, Gal 4:20). VI. The history of Isaac and Ishmael, by a comparison taken from which he illustrates the difference between such as rested in Christ and such as trusted in the law. And in all these, as he uses great plainness and faithfulness with them, so he expresses the tenderest concern for them.

4:18 Paul’s statement might mean that it was fine for people to seek the Galatians’ loyalty, but those other teachers were not in fact eager to do good things for them. Alternatively, this verse could be translated It is good to be always sought eagerly for good things, and not just when I’m with you. In this case it would mean that it was good for the Galatians to continue eagerly embracing Paul and his message and not change their attitude toward him in his absence.
