Hebrews chapter 12 builds on the example of the heroes of the faith mentioned in chapter 11. The main point of this lesson is that these figures endured suffering and hardship, yet held to their faith in God, which allowed them to achieve victory. Chapter 12, in particular, points out that earthly hardship is not a sign of God's displeasure, or abandonment. Rather, it's part of living in a fallen, godless world. And, in many cases, it's a form of ''training'' the Lord uses to mold us into more powerful instruments. This, as with other passages in Hebrews, leads into another explanation of why we should take these ideas seriously, and sets up a few final practical lessons in chapter 13 (BibleRef).
