Paul now moves from the good news about how people begin a relationship with God to the security of that relationship. Christians have a strong and lasting promise. This promise rests on God’s work in Jesus Christ, God’s love for them, and the power of the Holy Spirit.
This promise shapes the teaching in these chapters (5:1–11; 8:18–39). Paul explains it by showing that believers have been moved from the realm of Adam to the realm of Christ (5:12–21). Because of this change, no power can break this relationship. Sin (chapter 6), the law (chapter 7), or death (8:1–13) cannot separate believers from God’s love (8:39).
