Paul approaches his concluding words with a series of exhortations:
6:1: It is very easy for young Christians to become caught in various transgressions. Immature Christians also become entangled in sin. They drift away from fellowship with Christ because they become allured by the world, the flesh, and the devil. They are ignorant of God's Word, or casual about it. They neglect fellowship and prayer, and begin dallying with experiences they should leave alone. The mature believers (the "spiritual" ones, in Paul's language) should steer the straying Christian back onto the narrow road of righteousness. But the mature believers should approach this task gently. We should not harshly berate the stumbling brother, since that is likely to harden them against our appeals, and comes across as holier-than-thou. The mature Christians should also keep a watchful eye on themselves. No Christian is so infallibly godly that he or she is immune to temptation. Even the nurses serving in the wards could catch the germs.
6:2-5: Life can be hard. Christians should help each other when crushing loads of testing and temptation fall upon us. Christianity does not teach rugged individualism. We should not coolly look upon a staggering brother; we should come alongside and lift him or her up. Women tend to be better at this than men, but not always. Women also can be prone to gossip about one another's struggles, but not do anything about them. It takes humility to be helpful. Just as we are not above temptation, we are also not above helping our lowliest brothers. We should not look down on the weak brother. We are weak and lowly sinners, too. It is tempting to think more highly of ourselves than we ought to think,. by comparing ourselves to some perpetually-bumbling brother in the Lord. But we should evaluate ourselves only in light of the will of the Lord, not by comparing ourselves to others. At the judgment seat of Christ, we will all answer for how we handled our own loads which we bore in life -- not for anyone else's.
6:6: The teacher or preacher should be remunerated by those he serves. Young Christians need to be taught this, even though that makes a pastor feel uncomfortable (because it smacks of self-service). But the work of the church depends on the financial support of its people. Bills don't pay themselves.
6:7-10: It is impossible to get away with sin. God is not an inattentive overseer. He is the great king. People who laugh at Him end up suffering for it. God has built a law of sowing and reaping into the universe. This law has nothing to do with money. If a Christian by sinning cultivates his wicked, fallen flesh, then his flesh will produce spiritual ruin for him. If a Christian cultivates his spirit by persistently doing good, that will produce a crop of blessing for him. He will reap all the benefits of everlasting life. He works out his salvation with fear and trembling. Christ will also justify his saving faith by the evidence of his good works, as it says in James 2. Notice, however, that the responsibility for this rests on the believer. It doesn't simply happen as an automatic result of new birth.
