Albert Barnes Commentary Galatians 6:9

"And let us not be weary in well-doing: for in due season we shall reap, if we faint not." — Galatians 6:9 (ASV)

And let us not be weary in well doing. (See Barnes on 1 Corinthians 15:58).

The reference here is particularly to the support of the ministers of religion (Galatians 6:6); but the apostle makes the exhortation general. Christians sometimes become weary. There is so much opposition to the best plans for doing good; there is so much to be done; there are so many calls on their time and their charities; and there is often so much ingratitude among those whom they endeavor to benefit, that they become disheartened. Paul addresses such people and exhorts them not to give up, but to persevere.

For in due season. At the day of judgment. Then we shall receive the full reward of all our self-denials and charities.

We shall reap, if we faint not. This means if we do not give up, exhausted and disheartened. It is implied here that unless a person perseveres in doing good to the end of life, they can hope for no reward. The one who becomes disheartened, and who gives up their efforts; the one who is appalled by obstacles, and who faints because of the embarrassments thrown in their way; the one who pines for ease, and withdraws from the field of benevolence, shows that they have no true attachment to the cause, and that their heart has never been truly in the work of religion.

The one who becomes a true Christian becomes such FOR ETERNITY. They have enlisted, never to withdraw. They become pledged to do good and to serve God always.

No obstacles are to deter them, no embarrassments are to drive them from the field. With the rigor of their youth, and the wisdom and influence of their riper years; with their remaining powers when enfeebled by age; with the last pulsation of life here, and with their immortal energies in a higher world, they are to do good.

For that, they are to live. In that, they are to die; and when they awake in the resurrection with renovated powers, they are to awake to an everlasting service of doing good, as far as they may have opportunity, in the kingdom of God.
