The introductory so connects this verse with the one immediately preceding. In the light of what Paul has just said, he now defines for his readers and for himself a corresponding course of action.

The verbs translated become tired and give up are similar in meaning, both containing the elements of fatigue and exhaustion. The first verb puts emphasis on losing interest (for example, “spiritless”) and the second on becoming discouraged or relaxing one’s efforts. These are reflected in some translations (Revised Standard Version “grow weary … lose heart”; New American Bible “grow weary … relax our efforts”).

The word translated good is literally “well-being”; a different word for good is used in verse 10. Perhaps we should not press the distinction between these two words, but if one is to be made, doing good in this verse would refer generally to any action done for others or for oneself that results in well-being. In verse 10 it would refer primarily to things done for the benefit of others.

The last part of verse 9 suggests that Paul is thinking eschatologically. It could be that the time will come refers to the expected return of the Lord or to the end of the world. In place of this expression one may say, in some languages, “there will be a day,” or “the day will happen.”

An expression for reaping the harvest must refer to something beneficial or good. This may be expressed in some languages as “we will have the benefit of a harvest,” or “we will have a good harvest.”
