Galatians 6:9

Let us not be weary - Well-doing is easier in itself than ill-doing; and the danger of growing weary in the former arises only from the opposition to good in our own nature, or the outward hinderances we may meet with from a gainsaying and persecuting world.

In due season we shall reap - As the husbandman, in ploughing, sowing, and variously laboring in his fields, is supported by the hope of a plentiful harvest, which he cannot expect before the right and appointed time; so every follower of God may be persuaded that he shall not be permitted to pray, weep, deny himself, and live in a conformity to his Maker's will, without reaping the fruit of it in eternal glory. And although no man obtains glory because he has prayed, etc., yet none can expect glory who do not seek it in this way. This is sowing to the Spirit; and the Spirit and the grace are furnished by Christ Jesus, and by him the kingdom of heaven is opened to all believers; but only those who believe, love, and obey, shall enter into it.

And let us not be weary in welldoing - See the note at 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. Such Paul addresses, and exhorts them not to give over, 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 - If we do not give over, exhausted and disheartened. It is implied here, that unless a man perseveres in doing good to the end of life, he can hope for no reward. He who becomes disheartened, and who gives over his efforts; he that is appalled by obstacles, and that faints on account of the embarrassments thrown in his way; he that pines for ease, and withdraws from the field of benevolence, shows that he has no true attachment to the cause, and that his heart has never been truly in the work of religion. He who becomes a true Christian, becomes such for eternity. He has enlisted, never to withdraw. He becomes pledged to do good and to serve God always. No obstacles are to deter, no embarrassments are to drive him from the field. With the vigor of his youth, and the wisdom and influence of his riper years; with his remaining powers when enfeebled by age; with the last pulsation of life here, and with his immortal energies in a higher world, he is to do good. For that he is to live. In that he is to die; and when he awakes in the resurrection with renovated powers, he is to awake to an everlasting service of doing good, as far as he may have opportunity, in the kingdom of God.

6:9 But let us not be weary in well doing - Let us persevere in sowing to the Spirit. For in due season - When the harvest is come, we shall reap, if we faint not.
