Reflecting on the prior teachings about the deeds of the flesh versus the fruit of the Spirit, Paul encouraged the church of Galatia to not get discouraged in their doing good because they will soon reap a harvest!
1 Brothers and sisters, if someone is caught in a sin, you who live by the Spirit should restore that person gently. But watch yourselves, or you also may be tempted. 2 Carry each other’s burdens, and in this way you will fulfill the law of Christ. [Mark 12:29-31] 3 If anyone thinks they are something when they are not, they deceive themselves. 4 Each one should test their own actions. Then they can take pride in themselves alone, without comparing themselves to someone else, 5 for each one should carry their own load. 6 Nevertheless, the one who receives instruction in the word should share all good things with their instructor [1 Timothy 5:17-21].
7 Do not be deceived: God cannot be mocked. A man reaps what he sows. 8 Whoever sows to please their flesh, from the flesh will reap destruction; whoever sows to please the Spirit, from the Spirit will reap eternal life. 9 Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up. 10 Therefore, as we have opportunity, let us do good to all people, especially to those who belong to the family of believers [Matthew 25:31-46; 12:48-50].
