Summary: The contrast between the old nature and the new couldn't be more stark as we finish up our study in Paul's letter to the Galatians. The question we all have to face is: where is our treasure, in this legalistic age, or in God's kingdom?
Galatians is all about the contrast between the old nature and the new, legalism and Spirit-life. As we finish up the book today we’re going to see that contrast in stark relief so let’s look for it as we finish chapter 6.
As we talked about the fruit of the Spirit in chapter 5, we saw that a lot of it had to do with having God’s attitudes as our attitudes—overflowing love, looking to the good of others even if it is to our detriment, being patient, and basically laying ourselves and our needs before God in order to be used most effectively as an instrument of incredible good in the lives of others.
The conclusion of the letter of Galatians takes up that theme again, and puts it in opposition to the attitude of the Judaizers, who were only in it for themselves.
So to get up to speed with the flow of this new life, this transformative life that the Holy Spirit is birthing in us we see that we are becoming:
Not as prone to obeying the old nature
Overflowing with God’s self-sacrificing love
Seeking goodness in others
Seeking restoration in those who have fallen prey to the old nature
Now he tells the Galatians that a new-life person is also generous and grateful.
Just as those in the Galatian churches benefited spiritually by hearing the Word of God taught to them, they should in return benefit the teachers materially. Paul said in 1 Corinthians 9:9 (quickview)  “Do not muzzle the ox while it treads out the grain” as a way of encouraging believers to support their pastors. It’s a part of “carry one another’s burdens” of verse 2. We help carry the burden of assisting those in need and assisting those who are laboring in the gospel.
Now while verse 7 does have wider application, the specific context is in how you give of your time, talents, and money.
7 – 8
Another way of saying this is: “Don’t fool yourself. You certainly can’t fool God.” When you put your resources into that which condones or encourages the old nature that old nature is going to give back garbage. The word “corruption” means “decay”. On the other hand, giving of yourself – your money, time, and talent – to help spread the kingdom of God will reap eternal life in those who hear it. I’m certainly not saying we should give all of our money to the church but we should think about how we spend and what it will result in both in our lives and others.
I think there is indeed a wider application than just financial giving, however. This is one of those universal truths. If you make decisions that bolster the old nature that old nature is going to give back more of what it knows best: decay, corruption, death—things that pull you away from God. But if you sow to your new nature by “putting to death the deeds of the flesh” and instead do things that encourage growth in your relationship with God, you will get the natural result of that—a quality of life that is well beyond what this age can offer. Remember: “Where your treasure is, there will your heart be also.” (Matt 6:21 (quickview) )
