In Gal 6, Paul teaches us to examine your own work and test your own actions. Keeping in mind that we will reap what we sow, we should always sow unto the Spirit. We should always do good to all people, in a spirit of gentleness, bearing one another's burdens, and helping to restore those caught in any trespass. As Paul says, though, "may it never be that (we) would boast, except in the cross of our Lord Jesus Christ". Because of the cross, our interest in the ways of this world has been crucified. We have been transformed into a new creation with a new nature, by God's mercy and grace.
