This chapter is encouragement to the saints to live like we believe what the Bible says; opening with a description of faith. Biblical faith is key to our world-view and contrasts strikingly with walking by sight. But it’s important to reflect on the foundation which was laid in the preceding chapter – see verses 22-25. That passage exhorts us to faith, hope, and love which are part and parcel of our walk with the Lord. Chapter 11 develops faith, chapter 12 hope, and chapter 13 love. The suffering and perseverance of the saints summarized in chapter 10 are expounded with biblical examples in this chapter.
