The verse
Let us not grow weary in well-doing, for in due time we will reap a harvest if we do not give up.
Galatians 6:9 (BSB)
The short answer
Galatians 6:9 urges believers not to grow weary or lose heart in doing good, because a harvest is coming. Paul uses a farming image: good done now is seed sown, and God guarantees a reaping in His due season for those who do not give up. It promises a future reward, not immediate results.
Galatians 6:9 is a verse people reach for when they are tired of doing the right thing and seeing little for it: the parent who keeps showing up, the caregiver whose work goes unthanked, the believer who keeps serving while nothing seems to change. It promises that the effort is not wasted, that a harvest is coming.
But Paul did not write this line as a motivational slogan. He wrote it near the end of a heated letter to churches that were being pulled away from grace, and he set it inside a farming image that runs through the whole paragraph. To hear the real comfort of Galatians 6:9, we have to see the law of sowing and reaping that Paul is leaning on, and the patient timing he builds into it.
Where Galatians 6:9 sits in Paul's letter
Galatians is one of Paul's most urgent letters. He wrote to churches in the region of Galatia that were being unsettled by teachers insisting that faith in Christ was not enough, and that believers also had to take on the works of the law to be right with God. Paul's answer fills the letter: we are justified by faith in Christ, not by works, and the Christian life is meant to be lived by the Spirit, not by self-effort or rule-keeping.
By chapter 6 Paul turns from doctrine to daily life. He has just told them to carry one another's burdens (6:2), to do good to everyone, and especially to fellow believers (6:10). Verse 9 sits right in the middle of this practical section about how Spirit-led people actually treat each other. It is not an isolated promise of success; it is a charge to keep loving and serving when the doing of good has become tiring.
Paul is not promising worldly achievement here. He is steadying weary Christians who are tempted to quit the slow, unglamorous work of doing good to the people around them.
The law of sowing and reaping behind the verse
Verse 9 cannot be read without the two verses before it. In 6:7 to 6:8 Paul lays down a principle drawn straight from the field: "Do not be deceived: God is not mocked. Whatever a man sows, he will reap in return. The one who sows to please his flesh, from the flesh will reap destruction; but the one who sows to please the Spirit, from the Spirit will reap eternal life."
This is the logic that makes verse 9 true. Life works like a farm. Every action is a seed, and seeds grow into a harvest of the same kind. Sow to the flesh, to selfishness and sin, and the crop is decay. Sow to the Spirit, in obedience and love, and the crop is life. Paul is not being sentimental; he is stating a moral law as reliable as the agricultural one. God has built the universe so that good sown is never lost.
So when Paul says in verse 9, "let us not grow weary in well-doing," the "well-doing" is the sowing to the Spirit he just described. And the promised harvest is the reaping of life he just named. The encouragement is not vague positivity. It is the confidence that the God who guarantees a harvest to the farmer guarantees one to the faithful.

Why Paul says "do not grow weary"
Paul names a specific danger, and it is worth seeing the two words he uses. The first warns against weariness; the second, in the phrase "if we do not give up," warns against losing heart and quitting altogether. These are the two ways good people stop doing good: they get tired, and then they faint.
- egkakeoeng-kak-EH-o
- to grow weary, lose heart, become discouraged in a good work; to slacken because the effort is not yet paying off
- ekluoek-LOO-o
- to faint, to be unstrung or exhausted; the giving-up that follows weariness, like a runner collapsing before the finish
The picture is honest about how spiritual fatigue works. First the heart grows weary, worn down by doing good without seeing fruit. Then, if that weariness is not answered, it hardens into fainting, the quiet decision to stop. Paul is not scolding tired people. He is naming exactly where the well-doing usually dies, in the gap between sowing and harvest, and he plants his promise right in that gap.
Notice why we get weary in the first place: the harvest is not immediate. A farmer who needed his crop the same week he planted would give up every spring. Verse 9 is written for the long wait between the seed and the reaping.
What "in due season" promises and does not promise
The hinge of the whole verse is the phrase "in due season" or "at the proper time." Paul does not promise that the harvest comes quickly, on demand, or on our schedule. He promises that it comes at the right time, the time God appoints. Just as a field has its own season that cannot be rushed, the reaping of good has a set moment known to God alone.
This is why it matters not to read verse 9 as a guarantee of fast or visible results. It is not a formula that says do good and life will quickly reward you. Much of the harvest Paul has in view in 6:8 is eternal life, a crop that may not be fully gathered until we see Christ. Some good we do will bear visible fruit in this life; some will not be seen until the next. Either way, the promise holds: nothing sown to the Spirit is wasted.
- It does not promise a quick payoff. The harvest comes "in due season," the time God sets, not the time we want.
- It does not promise that doing good will make life easy or prosperous now. Paul himself suffered while sowing faithfully.
- It is not a transaction where we earn from God; the same letter insists we are saved by grace, not by works. The harvest is God's faithful reward to those already His, not wages we negotiate.
- It does promise, with God's own reliability, that faithful good is never lost and will surely be reaped.
Paul even attaches a condition, and it is the most encouraging part: "if we do not give up." The only way to miss the harvest is to stop sowing before it comes. The verse does not ask us to be strong or successful. It asks us to keep going.
How to keep doing good when you are tired
Galatians 6:9 meets you in the exact place it was written for: the weary middle, where you are still doing the right thing but no longer feel the reward of it. Paul's answer is not to try harder by sheer willpower. The whole letter has just told us the good comes from the Spirit, not the flesh. So keeping on is less about gritting your teeth and more about remembering the harvest and leaning on the One who supplies it.
Holding onto the promise in practice
- Preach the harvest to yourself. When the good you do feels pointless, remember Paul's law: a crop is coming. Visible fruit is not the measure; God's guarantee is.
- Loosen your grip on the timing. "In due season" means the reaping is on God's calendar, not yours. Let that free you from needing to see results now.
- Sow to the Spirit, not the flesh. The strength to keep going is something God supplies as you walk by the Spirit (Galatians 5:25), not something you manufacture alone.
- Watch the second danger. Weariness is normal; fainting is the trap. When you feel like quitting, that is precisely the moment verse 9 was written to carry you through.
Read this way, Galatians 6:9 is not a slogan for self-made success. It is a farmer's promise to tired servants of Christ: keep sowing the good, because the God who never mocks the field will give you a harvest in His time, and the only way to lose it is to stop.
A prayer
Father, I am tired of doing good and not seeing the fruit of it, and I am tempted to give up. Thank You that no good sown to Your Spirit is ever wasted, and that a harvest is coming in Your perfect time. By Your Spirit, keep me from growing weary and from losing heart. Help me to keep sowing, to trust Your timing, and not to give up before the reaping. Amen.

Frequently asked questions
What is the harvest Paul promises in Galatians 6:9?
It is the reaping Paul names in the verses just before it (6:7 to 6:8): the one who sows to the Spirit reaps eternal life. So the harvest is God's good reward to those who keep doing good, partly seen in this life and fully realized in the life to come. It is not a guarantee of worldly success.
What does "in due season" mean in Galatians 6:9?
It means "at the proper time," the season God appoints, not a quick or on-demand payoff. Like a field that cannot be rushed, the reaping of good comes when God determines. The phrase guards against expecting fast results and calls believers to patient trust in God's timing.
Is Galatians 6:9 about earning rewards from God?
No. The whole letter insists we are justified by faith in Christ, not by works of the law. Galatians 6:9 is not a transaction where we earn God's favor; it is His faithful promise that the good done by people already saved by grace will surely be rewarded in His time.
How is Galatians 6:9 different from Galatians 6:7?
Verse 7 states the principle: whatever a person sows, that they will reap. Verse 9 applies it as encouragement: since that law holds, do not grow weary in doing good, because the harvest is guaranteed for those who do not give up. One is the law of sowing; the other is the call to keep sowing.
