Theodore Epp emphasizes that as believers, our true citizenship is in heaven, and we should focus on heavenly things rather than earthly distractions. He draws parallels between the faith of the patriarchs and our current journey, urging us to seek the eternal city designed by God. Epp warns against those who prioritize earthly desires, labeling them as enemies of the cross, and encourages believers to align their thoughts with the teachings of Christ. He reminds us that while we live on earth, our lives should reflect our heavenly calling, as we await Christ's return with confidence.
