Paul directs us to imitate him. He draws out that there are two types of people you can watch: people who walk according to his gospel and those who walk as enemies of the cross. Who will you watch? Who you watch will influence who you worship. Because God is the only one deserving of worship, who you worship determines your future. If you are an enemy of the cross, your future is destruction. But it doesn't have to be! Paul is inviting you to imitate him, worship Jesus, and become a citizen of heaven.
