17 Brothers and sisters, become imitators of me and watch those who live this way—you can use us as models. 18 As I have told you many times and now say with deep sadness, many people live as enemies of the cross. 19 Their lives end with destruction. Their god is their stomach, and they take pride in their disgrace because their thoughts focus on earthly things. 20 Our citizenship is in heaven. We look forward to a savior that comes from there—the Lord Jesus Christ. 21 He will transform our humble bodies so that they are like his glorious body, by the power that also makes him able to subject all things to himself.
