17Join together in following my example, brothers and sisters, and just as you have us as a model, keep your eyes on those who live as we do. 18For, as I have often told you before and now tell you again even with tears, many live as enemies of the cross of Christ. 19Their destiny is destruction, their god is their stomach, and their glory is in their shame. Their mind is set on earthly things. 20But our citizenship is in heaven. And we eagerly await a Savior from there, the Lord Jesus Christ, 21who, by the power that enables him to bring everything under his control, will transform our lowly bodies so that they will be like his glorious body.
