In light of the examples of faith presented by the author of Hebrews, he encourages his readers to fix their eyes on Jesus and endure discipline.

Explanation:

The book of Hebrews in the New Testament was written by or traditionally attributed to Apostle Paul. This book contains, like most of his other letters, advice and also talks about how to live a life that will be acceptable to God.

In Hebrews chapter 3:1- 11, the author talks about endurance, discipline, and the importance of fixing one's goal to Christ and working towards achieving that goal. This is what faith must be, how faith should be, and how we must cling on to this faith in attaining our goal through God. Verse 7 says "Endure hardship as discipline; God is treating you as his children..." And by this endurance, we will be able to remain faithful to the promise of God's love and be one with Him.
