What does Galatians 6:11 mean?

For he who sows to his own flesh will from the flesh reap corruption. But he who sows to the Spirit will from the Spirit reap eternal life.

Let us not be weary in doing good, for we will reap in due season, if we don’t give up.

So then, as we have opportunity, let’s do what is good toward all men, and especially toward those who are of the household of the faith.

As many as desire to make a good impression in the flesh compel you to be circumcised; just so they may not be persecuted for the cross of Christ.

For even they who receive circumcision don’t keep the law themselves, but they desire to have you circumcised, that they may boast in your flesh.

But far be it from me to boast, except in the cross of our Lord Jesus Christ, through which the world has been crucified to me, and I to the world.
