We don't agree, this is why Paul's Gospel is true.
I think that I am probably looking at this a little differently than you are.
Here is a little bit more of that passage,
Galatians 6:7-8
7Do not be deceived: God cannot be mocked. A man reaps what he sows. 8The one who sows to please his sinful nature, from that nature will reap destruction; the one who sows to please the Spirit, from the Spirit will reap eternal life.
The problem, as I find it, is that Paul seems to contradict Paul here. In other places he says almost exactly the opposite of this when he teaches that a Christian can indeed sow to please his sinful nature whenever he wants to, without destruction. Here he teaches the opposite of his sinfest doctrine of eternal security. That is good, but it does not exactly fit his version of the gospel. Jesus taught that a true believer must keep the Law, but Paul teaches the opposite of that in his gospel, right?
Paul teaches the opposite of the following scriptures as well:
1 John 2: 3-6
3We know that we have come to know him if we obey his commands. 4The man who says, "I know him," but does not do what he commands is a liar, and the truth is not in him. 5But if anyone obeys his word, God's love is truly made complete in him. This is how we know we are in him: 6Whoever claims to live in him must walk as Jesus did.
1 John 3:4-10
4Everyone who sins breaks the law; in fact, sin is lawlessness. 5But you know that he appeared so that he might take away our sins. And in him is no sin. 6No one who lives in him keeps on sinning. No one who continues to sin has either seen him or known him. 7Dear children, do not let anyone lead you astray. He who does what is right is righteous, just as he is righteous. 8He who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil's work. 9No one who is born of God will continue to sin, because God's seed remains in him; he cannot go on sinning, because he has been born of God. 10This is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not a child of God; nor is anyone who does not love his brother.
Do you then obey the Law, Photizo? Do you even keep the Sabbath? Do you "walk as Jesus did"? Have you stopped sinning? Or are you perhaps following another gospel, Paul's gospel?
Decide for yourself.
